Toothache and abscess care at Lambton Dental
A severe toothache or a swelling around a tooth is usually a sign that a nerve or the bone around a tooth has become infected. At Lambton Dental in West Toronto the dentist assesses the tooth, controls the pain and, where needed, drains an abscess before providing a written plan for the definitive treatment.
What is a dental abscess?
A dental abscess is a pocket of infection at the root of a tooth or in the surrounding gum. It usually forms when the nerve inside a tooth has died — often because a deep cavity, a cracked tooth or an old failing filling has let bacteria reach the nerve — and the infection has spread through the tip of the root into the bone. The pain often builds over days and can be accompanied by swelling, a bad taste or a low-grade fever.
A severe toothache without visible swelling is usually a sign of an inflamed nerve rather than an abscess, but the initial treatment is similar: the dentist identifies which tooth is affected, controls the pain and plans a definitive treatment. That is usually root canal therapy to save the tooth or extraction if the tooth is beyond repair, and antibiotics if the infection warrants them.
When to book a same-day toothache visit
Book a same-day visit for toothache or abscess when:
- The pain is severe enough to stop you sleeping, eating or working.
- You have swelling around a tooth, on the gum or in the face.
- You have a bad taste in the mouth or a small pimple-like bump on the gum near a tooth.
- A tooth is very sensitive to hot or cold and the sensitivity lingers long after the stimulus is removed.
- You have a low-grade fever or feel generally unwell alongside a tooth problem.
If you have a broken tooth alongside the pain, see broken tooth repair. For a same-day appointment when the source of the pain is not yet clear, our same-day emergency page describes the visit. If your face or neck is significantly swollen, or you have difficulty swallowing or breathing, please go to a hospital emergency department.
What to expect at a toothache or abscess visit
Call ahead
Phone the office at (416) 666-3700 and describe the pain, any swelling and how long it has been going on. The team advises whether same-day care is needed.
Focused exam
The dentist gently examines the affected tooth and gum, taps the tooth to see if it is tender, and checks for looseness and swelling in the surrounding tissues.
Digital X-ray
A small X-ray of the affected tooth is taken to see the root, any abscess and the bone around it, so the diagnosis is clear before any treatment is planned.
Pain control and drainage
The dentist uses local anaesthetic and, where a clear abscess is present, drains it to release the pressure and settle the pain. If antibiotics are indicated, they are prescribed at the visit.
Definitive plan
The dentist explains the options for saving or replacing the tooth — usually root canal therapy and a crown, or extraction with a plan for replacement — and provides a written estimate before any larger treatment is started.
Aftercare
You go home with clear instructions on medications, when the pain should settle and any signs that would mean calling back sooner.
If your face or neck is significantly swollen, you have difficulty swallowing or breathing, or you feel unwell, please go to a hospital emergency department rather than waiting for a dental appointment.
After the pain is under control
Controlling the pain and, where needed, draining an abscess is only the first step. Once the acute infection has settled, the tooth still needs a definitive treatment. In most cases the dentist recommends root canal therapy to remove the infected nerve and preserve the tooth, followed by a crown to protect it long term. Where the tooth is beyond repair, extraction is planned with a written plan for replacement — often a single implant or a bridge.
The follow-up procedure is booked at your convenience. Antibiotics only treat the infection temporarily and do not remove the source, so the definitive step matters. The team helps line up any insurance predetermination needed for the follow-up so there are no surprises when the larger treatment is done.
Cost, insurance, and CDCP / IFHP coverage
The cost of a toothache or abscess visit depends on what is done — an emergency exam and X-ray, pain control, abscess drainage — and the fees follow the Ontario Dental Association suggested fee guide. The dentist provides a written estimate for any larger follow-up treatment before it is booked or started.
Most Canadian dental insurance plans cover emergency exams, X-rays and abscess care under a basic category, with root canal or extraction under the appropriate category. We direct-bill wherever your plan allows. Lambton Dental is also a provider for the Canadian Dental Care Plan (CDCP) and the Interim Federal Health Program (IFHP); coverage depends on eligibility.

For larger treatment plans, monthly payment plans through a third-party financing partner are available on approved credit — ask at your consultation or see our payment options.

Frequently asked questions about toothache and abscess
How do I know if I have a dental abscess?
The most common signs are a throbbing toothache, swelling of the gum or face near the affected tooth, tenderness when biting and a bad taste in the mouth. Some patients also notice a small pimple-like bump on the gum that occasionally drains. If you have any of these signs, call the office at (416) 666-3700 — the sooner the abscess is drained, the sooner the pain settles.
Will antibiotics fix a dental abscess on their own?
No. Antibiotics can settle the surrounding infection temporarily but they do not remove the source, which is inside the tooth. A definitive treatment — usually root canal therapy to save the tooth, or extraction if the tooth is beyond repair — is needed to prevent the infection from returning. Antibiotics are prescribed only when clinically indicated at the emergency visit.
Can I take painkillers while I wait for the appointment?
Over-the-counter ibuprofen or acetaminophen can help while you wait, if there are no reasons for you to avoid them. Rinsing gently with warm salt water and avoiding very hot or very cold food and drink may also ease the pain. Please tell the dentist at the visit what you have taken and when. Do not place aspirin directly on the gum — it can burn the tissue.
Is a toothache always an abscess?
No. A toothache can also come from a deep cavity that is close to the nerve, a cracked tooth, an inflamed nerve (pulpitis) without full infection, a loose filling or crown, or from the gum around a tooth. The dentist uses a focused exam and an X-ray at the emergency visit to identify exactly which of these is happening before planning treatment.
Can you save a tooth with an abscess?
Very often, yes. Root canal therapy removes the infected nerve from inside the tooth and seals the root, and a crown then protects the tooth from further breakage. The success rate is high in teeth that are otherwise structurally sound. Where the tooth is severely broken or the root is fractured, extraction and a plan for replacement is the more sensible next step.
Will I need time off work?
For the emergency exam, drainage and pain relief, most patients return to work the same day or the next day. A follow-up root canal or extraction is a longer visit and some patients prefer to take the rest of that day off. The dentist advises what to expect for your situation so you can plan the day around the appointment realistically.
Do you use sedation for toothache visits?
Yes, when appropriate. Nitrous oxide sedation is available for most emergency visits after the dentist reviews your medical history. Oral or IV sedation can be arranged for a follow-up visit where more extensive treatment is planned. See our sedation options page for a full explanation of the levels available at Lambton Dental.
