Dental Pain: What Are the Causes and When Should You See a Dentist?

Dental pain can appear at any time, ranging from mild discomfort to severe, unbearable pain. In many cases, it signals that something is wrong and requires professional attention. In this article, we explore the most common causes of dental pain, such as sensitivity, cavities, dental infections, and bruxism. We also provide tips to help you recognize when emergency care is necessary and highlight the importance of preventive care to avoid these issues.

Dental Sensitivity: Sharp and Localized Pain

Dental sensitivity often occurs when teeth come into contact with hot, cold, sweet, or acidic foods. This condition is commonly caused by:

• Wearing down of enamel
• Gum recession that exposes the dentin
• Overuse of whitening products

Tip: If you experience sensitivity, try a toothpaste formulated for sensitive teeth and visit your dentist if the symptoms persist.

Cavities: A Common and Preventable Cause

Cavities develop when bacteria in plaque and tartar produce acids that attack the enamel. They are painless at first, but without treatment, they can reach the dentin, making the tooth more sensitive. If the cavity progresses further, it can reach the center of the tooth and cause inflammation of the pulp, which can be painful and disabling.

Warning signs:

• Localized pain that worsens when eating or drinking
• Increased sensitivity to heat or cold

Prevention: Good oral hygiene and regular dental visits make it possible to detect cavities early, before they become painful.

Dental Infections: A Serious Problem

A dental infection, such as an abscess, can occur when bacteria reach the dental pulp or surrounding tissues. It can also develop under the gums when a foreign object is present or in cases of periodontal disease. These infections may cause throbbing pain, swelling of the mouth or face, and even fever.

When should you seek emergency care:

• Persistent and intense pain
• Presence of pus or a bad taste in the mouth
• Swelling of the face or difficulty opening the mouth

Prompt treatment, such as draining the abscess and taking antibiotics, helps prevent serious complications.

Bruxism and TMJ Disorders: Often Overlooked Sources of Pain

Bruxism, or teeth grinding, along with temporomandibular joint disorders (TMJ disorders), can cause diffuse pain in the jaw, teeth, or even lead to headaches.

Warning signs:

• Pain upon waking or after stressful periods
• Clicking or locking of the jaw
• Excessive tooth wear and sensitivity

Tip: A night guard, a custom-made device designed by your dentist to protect your teeth from grinding, can significantly reduce symptoms and prevent long-term damage. Your dentist will guide you toward the most suitable solution.

When Should You Seek Emergency Dental Care?

Some symptoms require immediate attention to avoid potentially serious complications:

• Sharp or throbbing pain that does not improve with pain medication
• Sudden swelling or signs of infection
• A fractured or accidentally lost tooth
• Significant bleeding after an extraction, surgery, or trauma

Dental pain is never pleasant or insignificant, but it can often be prevented with regular dental visits and proper daily care. If you experience any concerning symptoms like those described in this article, do not hesitate to schedule an appointment promptly with the Centre Dentaire de Haute Technologie du Québec.
