1. Why Cavities Develop Under Fillings

Many people believe that once a tooth is filled, it’s protected forever. However, cavities can still develop under or around dental fillings due to several factors.

Filling Wear and Tear

Over time, fillings can wear down, crack, or become loose, allowing bacteria to seep underneath and cause new decay. This is especially common in older silver amalgam fillings.

Poor Oral Hygiene

Even with a filling, plaque and bacteria can accumulate around the edges of the restoration, leading to decay if proper brushing and flossing habits are not maintained.

Gaps Between Filling and Tooth

As fillings age, tiny gaps can form between the filling material and the tooth structure. These spaces create perfect hiding spots for bacteria, increasing the risk of cavities.

2. Signs You Might Have a Cavity in a Filled Tooth

Detecting a cavity under a filling can be tricky, but there are key symptoms to watch out for.

Increased Tooth Sensitivity

If you notice sensitivity to hot, cold, or sweet foods, it could be a sign that decay is forming under your filling.

Tooth Pain or Discomfort

A persistent, dull ache or sharp pain when chewing might indicate that a cavity is developing under your filling.

Visible Dark Spots or Cracks

Dark discoloration, cracks, or gaps around the filling can suggest that bacteria have entered the area and caused further decay.

Bad Taste or Bad Breath

If you experience a lingering bad taste or persistent bad breath, it could be due to bacteria trapped under a damaged filling.

3. Treatment Options for Cavities in Filled Teeth

The right treatment for a cavity in a filled tooth depends on the severity of the decay and the condition of the existing filling.

Filling Replacement

If decay is caught early, your dentist may simply remove the old filling, clean out the cavity, and place a new filling.

Dental Crown

For more extensive decay, a crown may be required to cover and protect the remaining tooth structure after removing the damaged area.

Root Canal Treatment

If the decay has reached the tooth's pulp, a root canal may be necessary to remove the infected tissue and preserve the tooth.

Tooth Extraction (Last Resort)

In severe cases where the tooth is too damaged to be saved, extraction may be the only option. A dental implant or bridge can replace the missing tooth.

4. How to Prevent Cavities Under Fillings

Prevention is key to maintaining the health of your filled teeth and avoiding further cavities.

Maintain Excellent Oral Hygiene

Brush twice a day with fluoride toothpaste, floss daily, and use an antibacterial mouthwash to reduce plaque buildup.

Regular Dental Checkups

Visit your dentist every six months for professional cleanings and exams to catch potential issues early.

Avoid Sugary and Acidic Foods

Reducing your intake of sugary and acidic foods helps prevent bacteria from breaking down your tooth enamel.

Consider Sealants or Fluoride Treatments

Your dentist may recommend sealants or fluoride treatments to provide extra protection against decay.

5. When to See a Dentist for a Filled Tooth

If you experience pain, sensitivity, or notice any changes in your filled tooth, schedule a dental appointment immediately. Early intervention can save your tooth and prevent more costly treatments down the road.
