Comment soigner un abcès dentaire?
A tooth abscess is a painful bacterial infection that requires prompt intervention to protect your dental health. This pocket of pus can appear in different areas of the dentition and significantly affect your daily well-being.
Dental abscesses: causes and symptoms
Understanding the causes of a dental abscess and the early signs of an infection is essential to take action before the situation worsens. A tooth abscess will never disappear without proper treatment of the underlying dental issues provided by a dental professional.
What are the symptoms of a dental abscess?
Symptoms of a dental abscess often include sharp, persistent tooth pain that may radiate to the jaw or neck. It is common to observe the following signs:
- swelling in your face, gums, or cheek near the affected tooth;
- increased sensitivity during chewing or when in contact with hot and cold foods;
- the presence of a foul taste in the mouth caused by the pocket of pus;
- a mild fever or a general sense of malaise;
- difficulty swallowing or opening your mouth in severe cases.
What causes an abscess to form?
A tooth abscess is an infection that often has multiple factors, but it usually stems from bacteria accumulating in the internal tissues. An untreated dental cavity or deep tooth decay are among the most frequent causes of a dental abscess.
When the enamel is compromised, a hole in the tooth allows bacteria to penetrate the pulp, which can then infect the root of the tooth. Dental trauma, such as a cracked tooth, or gum disease can also encourage the infection and inflammation to spread to surrounding tissues.

Why is consulting a dental centre such as Lapointe important?
Consulting a qualified professional promptly is the only way to effectively get rid of the infection. In each of the 30 Lapointe Dental Centres across Quebec, we focus on the outcome we’re working towards while healing the abscess; however, each clinical case is unique and requires a proper, tailored approach.
The professionals who practice in these centres have the necessary expertise to identify the type of abscess, whether it is a periapical abscess (at the tip of the root) or a periodontal abscess (in the gum). Without rapid intervention by a dentist, this dental infection can spread to the jawbone or other parts of the body. A precise evaluation, often involving an X-ray, allows a quality care plan to be developed in order to relieve your mouth pain and stabilize your oral health.
Treatment options for a tooth abscess
The primary goal of abscess treatment is to treat the infection while preserving the integrity of your teeth whenever possible. Several treatment options may be proposed depending on the severity of the abscessed area.
Drainage of the abscess
A dentist may proceed with drainage to allow the pus to drain and immediately reduce the pressure. This procedure helps relieve dental pain quickly and cleans the area to limit the extent to which the infection can cause further damage.
Root canal treatment
A root canal treatment is often the preferred solution to save your tooth when the pulp is infected. This procedure involves removing the infected tissue inside the canal, then disinfecting and sealing the root of the tooth. A crown is sometimes necessary afterward to strengthen the tooth.
Tooth extraction
If the structure of the tooth becomes damaged by a deep cavity or the infection has spread too far, a tooth extraction may be inevitable. Professionals qualified in dentistry ensure that their patients receive all the information regarding replacement options, such as dentures or implantology.
Antibiotics
In some cases, especially if you have a fever or the untreated abscess threatens to spread, an antibiotic may be prescribed. While this medication helps the body fight the bacterial infection, it does not replace the treatments mentioned above for a dental abscess performed by the dentist.
Preventing a tooth abscess on a daily basis
Prevention remains the best tool to maintain good dental hygiene and avoid the toothache and infection associated with an abscessed tooth. Here are some essential habits for home oral care:
- Brush your teeth twice a day with a fluoride toothpaste.
- Use dental floss daily to dislodge bacteria around the gum line.
- Schedule regular general dentistry visits for a thorough exam and cleaning.
- Replace aging dental work such as worn fillings or crowns before they leak.
These essential habits reduce the risk of dental complications and prevent damage to the teeth and jawbone.

FAQ: Your questions about dental abscesses
It’s normal to have concerns when dental pain appears suddenly. Here are answers to some questions frequently asked by patients visiting Lapointe Dental Centres in Quebec.
Can a tooth abscess heal on its own?
No, a tooth abscess cannot heal without treatment. Even if the tooth pain seems to have temporarily subsided, this often means that the infection has destroyed the nerves or that the abscess has ruptured, allowing the pus to escape elsewhere. The infection in or around the tooth remains active and will continue to cause swelling and inflammation.
Is it covered under CDCP?
Yes, many dental abscess treatments, such as root canals and tooth extractions, are eligible for coverage under the Canadian Dental Care Plan (CDCP) for qualified beneficiaries. Because coverage can depend on your specific treatment plan and eligibility, we recommend confirming details with your dental professional at Lapointe Dental Centres to understand any potential out-of-pocket costs.
Is an abscessed tooth a dental emergency?
Yes, an abscessed tooth needs immediate attention, as the infection can spread rapidly. If you experience difficulty swallowing, a high fever, or significant swelling in your face, you should see a dentist as soon as possible.
What are the costs to treat an abscess?
The cost varies based on the complexity of the abscess treatment required, whether it is drainage, a root canal, or an extraction. Lapointe Dental Centres offer flexible payment options and financing to ensure access to dental care for your well-being.
