Repair Cavities and Restore Your Natural Tooth

A small cavity can become a much bigger dental problem if it continues to grow. A dental filling removes damaged or decayed tooth structure and restores the tooth so you can comfortably bite, chew, and smile.

At Harte Dental in Milton, Massachusetts, we provide dental fillings for children, teens, and adults as part of our comprehensive family dental care. Our goal is to identify tooth decay early, preserve as much healthy natural tooth structure as possible, and provide a restoration that is comfortable, functional, and natural-looking.

If you have a cavity, tooth sensitivity, a broken filling, or simply haven't had your teeth checked recently, schedule an appointment with Harte Dental. We are accepting new patients.

What Is a Dental Filling?

A dental filling is a restoration used to repair a tooth that has been damaged by decay, minor fractures, or wear.

When you have a cavity, bacteria have damaged part of the tooth structure. Your dentist removes the affected tooth structure and replaces it with a restorative material.

The filling helps:

• Restore the tooth's shape

• Restore normal chewing function

• Protect the remaining tooth structure

• Seal the treated area

• Prevent food and bacteria from accumulating in the cavity

• Preserve your natural tooth

Treating decay while it is relatively small can often allow for a more conservative restoration.

What Causes Cavities?

Cavities, also known as dental caries or tooth decay, develop when bacteria in dental plaque interact with sugars and other fermentable carbohydrates in your diet.

These bacteria produce acids that can gradually weaken and break down tooth enamel.

Your risk of developing cavities can be influenced by several factors, including:

• How frequently you consume sugary or acidic foods and drinks

• Plaque accumulation

• Brushing and flossing habits

• Fluoride exposure

• Dry mouth

• Certain medications

• Deep grooves in the teeth

• Existing dental restorations

• Individual susceptibility to tooth decay

Regular dental examinations are important because cavities don't always cause symptoms when they first develop.

How Do I Know If I Have a Cavity?

One of the biggest misconceptions about tooth decay is that a cavity will always hurt.

It may not.

Early cavities can develop without noticeable symptoms. This is one reason routine dental examinations and appropriate dental X-rays can be valuable for detecting decay before it becomes larger.

As a cavity progresses, you may notice:

• Sensitivity to cold

• Sensitivity to sweets

• Sensitivity to heat

• Toothache

• Pain when biting or chewing

• Food repeatedly getting caught around a tooth

• A rough area or visible hole in a tooth

• Dark or discolored areas

• A broken or chipped tooth

However, having no pain does not necessarily mean that a tooth is healthy.

Do All Cavities Need Fillings?

No. Treatment depends on how far the decay has progressed.

Very early tooth decay that has not yet formed a physical cavity may sometimes be managed with preventive strategies designed to strengthen the enamel and reduce the risk of progression.

Once enough tooth structure has been lost that an actual cavity has formed, however, the missing tooth structure generally cannot simply grow back.

A dental filling is one of the most common ways to repair this damage.

At Harte Dental, we evaluate the tooth and recommend treatment based on the extent and location of the decay rather than simply treating every suspicious area the same way.

Can a Cavity Heal Itself?

This depends on what stage the decay has reached.

Early enamel demineralization may sometimes be stopped or remineralized before a physical cavity forms. Fluoride, improved oral hygiene, dietary changes, and professional preventive care can all play a role.

However, once tooth structure has been physically lost and a hole has formed, the tooth cannot regenerate that missing structure on its own.

At that point, restorative treatment such as a filling may be necessary.

This is another reason detecting tooth decay early matters.

Tooth-Colored Dental Fillings

Modern restorative dentistry allows many cavities to be repaired using tooth-colored composite resin fillings.

Composite material can be carefully selected and shaped to blend with the surrounding tooth.

Depending on the clinical situation, tooth-colored fillings can provide both functional and cosmetic benefits while allowing your dentist to preserve healthy tooth structure.

The appropriate restorative material depends on the tooth, location and size of the cavity, bite forces, existing restorations, and other clinical considerations.

What Happens When You Get a Dental Filling?

1. Your Tooth Is Evaluated

Your dentist examines the tooth and determines the extent of the decay or damage.

Dental X-rays may be recommended when necessary to evaluate areas that cannot be adequately assessed through a visual examination alone.

2. The Tooth Is Numbed

When appropriate, local anesthetic is used to numb the tooth and surrounding area so you remain comfortable during treatment.

3. Decay Is Removed

The damaged or decayed portion of the tooth is carefully removed while preserving as much healthy tooth structure as possible.

4. The Tooth Is Restored

The prepared area is filled with the appropriate restorative material.

For composite fillings, the material is placed and shaped to recreate the natural contours of your tooth.

5. Your Bite Is Checked

Your dentist checks how your teeth come together and makes adjustments when necessary.

The restoration is then finished and polished.
