Emergency Dentist in Markham: What to Do When Dental Pain Strikes at Night

It is 11:30 PM on a Sunday. You were fine at dinner, and now you have a throbbing toothache so severe you cannot sleep. The pain is building, not fading. You are not sure whether this can wait until Monday morning or whether you need to do something right now.

This is one of the most common dental emergency scenarios Markham patients face, and the uncertainty it creates is often as distressing as the pain itself. Do you go to the ER? Do you call someone? Do you take something and try to sleep?


This guide gives you clear, evidence-based answers for exactly this situation what to do at home to manage pain and swelling before you can see a dentist, how to know when it genuinely cannot wait, and where to find after-hours dental care in Markham and Unionville tonight.


Why Is Toothache Worse at Night?

If you have ever had a toothache that seemed manageable during the day but became unbearable the moment you lay down to sleep, you are not imagining it. There is a genuine physiological reason why dental pain intensifies at night.

When you lie down, blood flow to the head increases relative to when you are upright.


This increased blood pressure in the tissues around an inflamed or infected tooth creates greater pressure on the already-irritated nerve intensifying the pain signal significantly. During the day, the distraction of normal activity and the upright position both reduce the perceived intensity of the pain. At night, lying flat, in silence, with nothing else to focus on, the same pain feels dramatically worse.

Additionally, nighttime is when the body's natural cortisol levels drop cortisol has an anti-inflammatory effect, and lower levels at night can allow inflammation to flare more acutely.


Understanding this helps calibrate your response: pain that spikes severely at night but was manageable during the day is not necessarily worse disease but it does indicate that an infection or significant inflammation is present that warrants dental attention promptly, even if the severity fluctuates.


Can I Go to the ER for Tooth Pain?

This is the most searched question in after-hours dental care and the honest answer is nuanced.


Ontario ERs generally do not perform routine dental procedures like extractions and have no on-site dentist in most cases. For the majority of dental pain situations, visiting a hospital emergency room in Markham will result in pain medication, possibly antibiotics if infection is suspected, and a referral to see a dentist. The underlying dental problem the cavity, the infected pulp, the abscess will not be treated at the ER. Mclevindental

This means going to the ER for a toothache will typically cost you several hours in a waiting room, result in temporary pain relief, and still leave you needing a dental appointment to actually address the cause.


Go to a hospital ER instead of a dentist when:

  • You have difficulty breathing or swallowing this indicates the infection may be spreading toward the airway, a potentially life-threatening situation

  • You have rapidly spreading facial or neck swelling particularly if it is progressing toward the eye or distorting the neck

  • You have a high fever above 38.3°C (101°F) with dental pain this indicates a spreading systemic infection that needs medical assessment, not just pain management

  • You have uncontrolled bleeding from the mouth that does not stop after 20 minutes of firm pressure

  • You have a suspected broken jaw or significant facial trauma from an accident or injury

  • You have any neurological symptoms alongside dental pain confusion, severe headache, visual changes

For Markham and Unionville residents, go directly to Markham Stouffville Hospital Emergency at 381 Church Street (905) 472-7000. For life-threatening symptoms, call 911.


Go to an emergency dentist (not the ER) for:

  • Severe toothache without the above danger signs

  • A knocked-out or broken tooth

  • Lost crown or filling with severe pain

  • Dental abscess with localised swelling (not spreading rapidly)

  • Broken denture or orthodontic appliance causing injury

  • Post-extraction bleeding that persists but is not life-threatening

For any of these situations, contacting Hwy7 Family Dentistry at (905) 604-1995 for a same-day or next-available appointment, or accessing an after-hours provider, is the appropriate pathway.



What Is the Fastest Way to Stop a Toothache?

While no home remedy addresses the underlying cause of a toothache which requires dental treatment several measures provide genuine, meaningful temporary relief while you wait for your appointment.


1. Ibuprofen + Acetaminophen Combination (Most Effective)

The single most effective over-the-counter approach for dental pain is not a choice between ibuprofen and acetaminophen it is taking both together in alternating doses.

Current American Dental Association guidance on acute dental pain management supports this combination: ibuprofen addresses the inflammatory component of dental pain (the prostaglandins driving nerve irritation and swelling), while acetaminophen addresses the pain signal centrally through a different mechanism. The combined effect is significantly greater than either medication alone.


Recommended protocol:

  • Take ibuprofen 400 mg every six hours

  • Take acetaminophen 500 mg at the three-hour mark between ibuprofen doses

  • Continue alternating at three-hour intervals

Stay within label-maximum daily limits 1,200 mg ibuprofen per day for OTC use, and 3,000–4,000 mg acetaminophen per day. Always check with a pharmacist if you have kidney disease, liver disease, stomach ulcers, are pregnant, or are taking blood thinners or other medications.


Do not place aspirin directly against the gum this causes a chemical burn to the soft tissue and is one of the most common harmful home remedies for toothache. The Canadian Dental Association explicitly warns against this.


2. Cold Compress Not Heat

Apply a cold compress or ice pack wrapped in a cloth to the outside of your cheek 15 minutes on, 15 minutes off. Cold reduces swelling and numbs the area.

Do not apply heat to a toothache. Heat increases blood flow to the area, can accelerate the spread of infection, and consistently makes dental pain worse rather than better. The CDA explicitly warns: do not put a heating pad, hot water bottle, or any other source of heat on your jaw.


3. Sleep With Your Head Elevated

Rather than lying flat which increases blood pressure to the head and worsens dental pain sleep propped up on two or three pillows, or in a reclining chair if the pain is severe enough. Keeping the head elevated above the heart level reduces the throbbing pressure that intensifies pain in the lying-down position. This single adjustment can make the difference between sleeping and not sleeping when dental pain strikes at night.


4. Warm Salt-Water Rinse

Dissolve half a teaspoon of table salt in a glass of warm (not hot) water and rinse gently around the affected area for 30 seconds, then spit. Repeat several times. Salt water has mild antibacterial properties and helps reduce soft tissue inflammation. It is safe and appropriate for almost any dental pain situation.

Do not use a salt rinse if you have had a recent extraction and the socket is still actively bleeding the rinsing action can dislodge the clot.


5. Clove Oil (Eugenol)

Clove oil contains eugenol a naturally occurring compound with genuine topical anaesthetic and antibacterial properties, used in dentistry for over a century. Apply a small amount of clove oil to a clean cotton ball or cotton swab and dab it directly on the affected tooth and surrounding gum tissue.

Clove oil is available at most Markham pharmacies. It provides short-term numbing that can make the difference between sleeping and not sleeping while you wait for your appointment. A small amount goes a long way excessive application can cause soft tissue irritation.


6. OTC Topical Benzocaine Gel

Products such as Orajel contain benzocaine a topical anaesthetic that temporarily numbs the surface of the tooth and gum. Apply directly to the affected area according to package instructions. Effects are short-lived (15–30 minutes) but useful for immediate acute relief.

Note: benzocaine gel is not recommended for children under two years of age. For older children and adults, it is safe for short-term use.


7. Avoid Triggers

While waiting for your dental appointment, avoid:

  • Very hot or very cold food and drinks temperature extremes intensify nerve sensitivity in an inflamed or infected tooth

  • Chewing on the affected side

  • Sugary food and drinks bacteria metabolise sugar and produce acid that exacerbates infection

  • Alcohol has a mild anaesthetic effect in very high amounts but is not safe, effective, or recommended as dental pain management and can worsen dehydration


Managing Swelling Alongside Dental Pain

Swelling alongside dental pain indicates infection has spread beyond the tooth into the surrounding tissue a more serious situation requiring dental assessment as soon as possible.


Localised swelling (only around the affected tooth or a small area of gum): This is typical of a dental abscess and requires same-day dental attention. Apply a cold compress externally as described above. Do not attempt to drain the swelling at home this can introduce additional bacteria and spread the infection. Warm salt-water rinses help draw out minor infection naturally.


Rapidly spreading swelling (spreading toward the eye, cheek, or neck): This is a medical emergency requiring immediate hospital assessment, not dental care. If swelling is visibly progressing from one area to another over the course of an hour or two, if it is causing difficulty opening your mouth fully, or if it is associated with fever above 38.3°C (101°F), go directly to Markham Stouffville Hospital ER at 381 Church Street or call 911.


The 48-hour rule for dental swelling: Any visible facial swelling from a suspected dental source that has not improved after 48 hours of pain management or that is getting worse rather than better requires urgent dental assessment regardless of the absence of other alarm symptoms.

When Dental Pain Can Wait Until Morning and When It Cannot

One of the most practical judgments a patient needs to make at 2 AM is whether to act immediately or manage symptoms overnight and call the dentist at opening. Here is a clear framework:


Can reasonably wait until morning (with pain management as above):

  • Moderate toothache that responds partially to ibuprofen/acetaminophen

  • Lost filling or crown with sensitivity but no severe pain

  • Broken tooth with a sharp edge but no active pain or bleeding

  • Mild gum swelling without fever or rapid spreading

  • Loose tooth (in an adult) without acute pain


Should be seen as soon as possible call at opening, seek after-hours care if available:

  • Severe, unrelenting pain that does not respond to maximum OTC pain relief

  • Dental abscess with visible localised swelling

  • A lost filling or crown with significant exposed nerve pain

  • Any swelling that was not present at bedtime but developed overnight

  • Pain that woke you from sleep and will not allow you to return to sleep


Requires immediate action do not wait for morning:

  • High fever (above 38.3°C / 101°F) with dental pain or swelling

  • Rapidly spreading facial or neck swelling

  • Difficulty breathing or swallowing

  • Severe uncontrolled bleeding

  • Suspected jaw fracture or significant trauma

Dental Pain at Night With Children: What Parents Should Know

Children often find it more difficult to communicate the severity of dental pain, and nighttime toothache in a child can be particularly distressing for the whole household.

For children experiencing dental pain at night:


  • Pain management: Ibuprofen (children's formulation, weight-appropriate dose) or acetaminophen (not both together unless directed by a pharmacist) never aspirin in children or teenagers due to Reye's syndrome risk

  • Cold compress externally to the cheek

  • Elevate the head with an extra pillow

  • Do not apply topical benzocaine (Orajel) to children under two without medical advice

If your child has visible facial swelling, fever, or seems unwell beyond the tooth pain itself, seek medical attention promptly dental infections can progress more rapidly in children than in adults.


Book your child with a paediatric dentist in Markham at first opportunity the following morning. For guidance on managing anxiety around dental visits for children, see our kids' dental anxiety guide.


Build a Dental Pain Kit Before You Need One

The best time to prepare for a nighttime dental emergency is before it happens. Keep the following items accessible at home:


  • Ibuprofen 400 mg tablets

  • Acetaminophen 500 mg tablets

  • Clove oil (eugenol) available at most Markham pharmacies

  • Clean gauze pads

  • OTC temporary dental cement (Dentemp)

  • Orthodontic wax

  • A small lidded container (for knocked-out tooth storage in milk)

  • Hwy7 Family Dentistry saved in your phone: (905) 604-1995

  • Health811 saved in your contacts: 811

  • Markham Stouffville Hospital ER: (905) 472-7000


Having this kit prepared means you spend zero time searching for supplies and can focus entirely on managing the situation.


Frequently Asked Questions


Can I go to the ER for tooth pain in Markham? For most toothache situations, an emergency dentist is the appropriate first call Ontario ERs generally do not perform dental procedures and cannot treat the underlying cause of tooth pain. You will typically receive pain relief and antibiotics at the ER and be referred back to a dentist. Go to Markham Stouffville Hospital ER if you have difficulty breathing or swallowing, rapidly spreading facial or neck swelling, high fever above 38.3°C, uncontrolled bleeding, or suspected jaw fracture. For all other dental pain, call an emergency dentist.


What is the fastest way to stop a toothache? 

The most effective immediate approach is the ibuprofen-plus-acetaminophen combination take ibuprofen 400 mg and alternate with acetaminophen 500 mg at three-hour intervals. Apply a cold compress externally (never heat), sleep with your head elevated to reduce blood pressure to the area, rinse with warm salt water, and apply clove oil or OTC benzocaine gel directly to the affected tooth for topical numbing. These measures address the pain signal from multiple angles simultaneously.


Is it a dental emergency if I wake up with tooth pain at night? 

Dental pain that is severe enough to wake you from sleep or to prevent you from returning to sleep indicates significant underlying inflammation or infection that warrants same-day dental assessment when the practice opens. If the pain is accompanied by fever, facial swelling, or difficulty swallowing, treat it as an immediate emergency rather than waiting until morning. For pain that is manageable with OTC medication, call your dentist at opening and request the first available emergency slot.


What should I do about a toothache on a long weekend in Markham? 

Manage pain with ibuprofen and acetaminophen alternating, cold compress, elevated sleep position, and clove oil. If the pain is severe or accompanied by swelling or fever, contact an extended-hours provider Emergency Dental Office at (289) 302-6864 is open until 10 PM weekdays and Saturdays, and EmergDENT is open until midnight every day. For after-hours guidance, dial 811 for free nurse triage. For life-threatening situations, go to Markham Stouffville Hospital ER at 381 Church Street.


Can I take antibiotics I have at home for a toothache? 

Do not self-prescribe antibiotics. The Canadian Dental Association advises that antibiotics should only be taken if there is fever or swelling outside the face and even then, only under dental or medical supervision. Antibiotics do not address the structural cause of dental pain (a cavity, infected pulp, or abscess) and do not substitute for definitive treatment. If you have antibiotics leftover from a previous prescription, do not use them without consulting a dentist or pharmacist.


Does dental pain mean I have an abscess? 

Not necessarily many types of dental pain (cavities, cracked teeth, gum recession, sensitivity) occur without abscess formation. Dental abscess is specifically a collection of bacterial infection producing pus, usually accompanied by visible swelling at the gum or face, a persistent bad taste, and pain that is not well-controlled by standard OTC medication. If you have any of these signs alongside dental pain, treat it as a priority same-day dental concern rather than monitoring at home.
