Cavity Fillings in San Antonio TX

Tooth-colored cavity fillings in San Antonio's Medical Center District, with Dr. Chris Cappetta, DDS, a member of the Academy of General Dentistry with over 35 years of experience.

A Cavity Is Not a Failure. Waiting on It Is.

Cavities are the most common dental problem in adults and one of the most preventable. When decay is caught early, a filling is a straightforward one-appointment procedure that takes less than an hour and resolves the problem completely. When decay is left to progress, the same tooth that could have been saved with a filling may eventually need a root canal, a crown, or an extraction. Patients from Kirby and China Grove call Fountain of Youth Dental because Dr. Cappetta, DDS, a general dentist in San Antonio with over 35 years of experience, catches cavities at the stage where a filling is still the right answer.

Fountain of Youth Dental places tooth-colored composite resin fillings exclusively. No metal. No amalgam. The composite material is matched to the color of the surrounding tooth so the restoration is invisible in normal conversation and invisible in the mirror. More importantly, composite bonds directly to the tooth structure, which means less healthy tooth material needs to be removed to prepare the cavity compared to amalgam alternatives.

What Causes Cavities and How They Progress

A cavity begins when bacterial plaque produces acid that breaks down tooth enamel. In the earliest stage the enamel is softening but has not yet formed a hole. At this point fluoride and improved oral hygiene can sometimes reverse the process without a filling. Once a true cavity forms, the decay will continue to advance unless it is removed and the tooth is restored. Left untreated, the decay reaches the dentin layer beneath the enamel where it spreads faster and causes sensitivity. When it reaches the pulp at the center of the tooth, infection sets in and the tooth requires a root canal or extraction.

The progression from small cavity to major problem takes months to years depending on the individual. Patients who attend regular exams give Dr. Cappetta the chance to find decay at its earliest stage when treatment is simplest and least expensive. Patients who skip exams often discover their cavity at the point where a filling alone is no longer an option. Catching decay early is not just about convenience. It is about keeping the tooth intact long-term.

What to Expect at Your Filling Appointment

A cavity filling appointment at Fountain of Youth Dental typically takes 45 to 60 minutes depending on the size and location of the cavity. The tooth and surrounding area are numbed with local anesthesia before any work begins. Most patients feel pressure during the procedure but no pain. Dr. Cappetta removes the decayed material, shapes the cavity to receive the composite resin, places and cures the filling in layers, then checks and adjusts the bite before you leave.

Tooth-colored composite fillings are placed and cured at the same appointment. There is no temporary filling and no return visit for the final restoration. After the anesthesia wears off, most patients notice mild sensitivity to hot, cold, and pressure for a few days. This is normal and resolves on its own. If sensitivity persists beyond a week or worsens rather than improves, contact the office. Dr. Cappetta reviews post-care instructions before you leave so there are no questions about what to expect.

Cavity Filling in San Antonio, TX

Who Is a Good Candidate for a Tooth-Colored Filling

Most patients with a cavity are good candidates for a composite resin filling, but the size and location of the decay matter. Composite works best for small to moderate cavities on any tooth and for minor chips or cracks where the bulk of the tooth structure is still intact. Front teeth and visible teeth are natural fits because composite can be matched precisely to the surrounding enamel. Back teeth are equally appropriate for composite when the cavity is not too large, though very large cavities on molars that handle heavy chewing pressure may be better served by a porcelain inlay or onlay for added durability.

Patients who want to replace old metal amalgam fillings are also strong candidates for composite, with one important caveat. Dr. Cappetta evaluates the tooth first to confirm what is underneath the existing filling before removing it. Large old amalgam fillings sometimes conceal cracking or decay in the surrounding tooth structure that rules out a direct composite replacement and points toward an inlay, onlay, or crown instead. That evaluation happens at the exam before any work is scheduled. Patients who have significant bruxism or grinding may also need a night guard alongside their filling to protect the restoration long-term.

When Do You Need a Filling vs a Crown

Not every damaged tooth needs the same treatment, and one of the most common points of confusion patients bring to Fountain of Youth Dental is not knowing the difference. The table below shows which situations call for a filling, which call for a crown, and why the distinction matters clinically.

Situation Right Restoration Why
Small to moderate cavity with healthy surrounding structure Filling Enough tooth remains to support a direct restoration
Chip or minor fracture with the bulk of the tooth intact Filling Conservative approach removes only what is damaged
Small existing filling that has worn or failed Filling Tooth underneath is healthy and can support a new restoration
Large cavity where a filling would cover more than half the tooth surface Crown Filling alone cannot structurally support what remains
Tooth that has had a root canal Crown Root-treated teeth become brittle and need full coverage protection
Crack putting the tooth at risk of splitting under pressure Crown A filling cannot stabilize a fracture line
Old large amalgam filling that has cracked the surrounding tooth structure Crown or inlay/onlay Expansion and contraction over years fractures the enamel around the filling

The most common case Dr. Cappetta sees where a patient arrives expecting a simple filling and leaves with a different recommendation is a back molar with an old large amalgam filling that has cracked the surrounding tooth structure over years of use. The filling may look intact on the surface but the tooth around it has fractured. Catching this on imaging before the tooth splits is exactly the kind of finding that separates a filling appointment from a dental crown procedure, and in some cases from losing the tooth entirely. Dr. Cappetta explains what he finds and why before recommending anything.

How Much Do Cavity Fillings Cost in San Antonio TX

A tooth-colored composite filling at Fountain of Youth Dental typically runs $150 to $300 per tooth depending on the size and location of the cavity. Larger cavities that require more material and more preparation time run toward the higher end of that range. Back molars that handle heavy chewing pressure sometimes require slightly more complex placement. Dr. Cappetta provides a clear cost estimate at the exam before any treatment is scheduled so there are no surprises.

Most PPO dental insurance plans cover fillings at 70 to 80 percent after the deductible because they are classified as basic restorative procedures. Some plans distinguish between composite and amalgam fillings and cover composite at a lower rate. Fountain of Youth Dental verifies your benefits before the appointment and explains exactly what your plan covers before work begins. Financing is available for patients managing multiple fillings or who are uninsured.

Frequently Asked Questions

Do cavity fillings hurt?

The tooth and surrounding tissue are fully numbed with local anesthesia before any work begins. You will feel pressure during the procedure but not pain. The anesthesia injection itself may cause a brief sting that passes quickly. After the appointment, mild sensitivity to temperature and pressure is normal for a few days while the tooth settles. Over-the-counter pain relievers manage it easily for most patients. If the sensitivity increases or does not resolve within a week, call the office.

How long do composite fillings last?

With proper care, tooth-colored composite fillings last seven to ten years on average. Some last longer depending on the size of the filling, its location in the mouth, and how well the patient maintains their oral hygiene and attends routine exams. Back teeth that handle more chewing pressure wear fillings faster than front teeth. Dr. Cappetta checks the condition of all existing fillings at your routine exams so any wear or leaking margins are caught before decay restarts underneath.

Can I eat normally after a filling?

Wait until the anesthesia has fully worn off before eating to avoid accidentally biting your cheek, lip, or tongue while numb. Once sensation returns, most patients can eat normally. For the first 24 hours, avoid very hard or sticky foods that could stress the new filling before it has fully set. Composite resin fillings are cured with a light at the appointment and are fully hardened before you leave the office, so the restriction is primarily about comfort during the numbness period rather than the filling itself.

Can an old metal filling be replaced with a tooth-colored one?

Yes. Fountain of Youth Dental replaces old amalgam fillings with composite resin for patients who want a natural-looking restoration or who are concerned about the appearance of metal in their smile. The old filling is removed, the cavity is evaluated for any new decay or cracking underneath, and the composite filling is placed at the same appointment. Dr. Cappetta evaluates the tooth first to confirm whether a direct composite filling is appropriate or whether the size of the existing restoration makes an inlay, onlay, or crown the better long-term option.
