Dental Fillings

A dental filling is a restoration used to repair a tooth damaged by a cavity. Decay softens and breaks down the hard enamel structure of a tooth, and without treatment it keeps spreading inward. A filling stops that process: the decayed material is removed, and the remaining space is sealed so the tooth can function normally again. At Dentiq Dentistry in Houston, we use tooth-colored composite resin that matches your natural enamel rather than standing out against it.

If a cavity is left alone long enough, it eventually works through the enamel and into the softer dentin underneath, and then potentially to the inner pulp where the nerve lives. Once decay reaches the nerve, a filling is no longer enough — a root canal becomes the likely next step. Catching decay early and placing a filling is almost always simpler, faster, and less expensive than treating the same tooth after it has progressed.

Who Needs a Dental Filling

Fillings are appropriate for teeth with cavities that have not yet reached the nerve. Most people develop at least a few cavities over the course of their lives, so fillings are among the most routine procedures in dentistry. You might need a filling if your dentist finds decay on an X-ray during a routine exam, if you notice sensitivity to cold or sweet foods, or if you feel a rough spot or small hole on a tooth surface. Some cavities cause no pain at all in their early stages, which is one reason regular checkups matter — a small cavity found at an exam is far easier to treat than one discovered because it started hurting.

Beyond new decay, fillings are also sometimes used to replace old restorations that have worn down, cracked, or begun to leak around the edges over time.

What Happens During a Filling Appointment

A typical filling appointment at Dentiq Dentistry takes roughly 30 to 60 minutes for a single tooth, though that can vary depending on the size and location of the cavity.

The general sequence looks like this:

• **Numbing the area.** A local anesthetic is applied to the gum tissue first, then injected near the tooth so you don't feel the work being done.
• **Removing the decay.** A dental handpiece or laser removes the softened, infected tooth structure until only healthy enamel and dentin remain.
• **Preparing the surface.** The area is cleaned and conditioned so the composite resin will bond securely to the tooth.
• **Placing the composite.** The tooth-colored resin is applied in layers, with each layer hardened using a curing light.
• **Shaping and polishing.** The filling is adjusted so your bite feels natural, then polished smooth.

You can expect some numbness in the lip and cheek for a few hours afterward. Mild sensitivity around the treated tooth for a day or two is normal and typically resolves on its own.

Why Tooth-Colored Composite Resin

Composite resin has largely replaced older silver amalgam fillings for most routine cavities. The material bonds directly to the tooth structure, which means less of the natural tooth needs to be removed during preparation. Because it is matched to the shade of your enamel, a composite filling is not visible when you talk or smile. It is also mercury-free, which some patients prefer.

Composite resin does its job well in most locations, though very large restorations on back molars that take heavy chewing forces may sometimes call for a different approach — your dentist will discuss the best option if that applies to your situation.

Keeping Fillings Lasting as Long as Possible

Composite fillings generally last many years with normal care. Brushing twice a day, flossing daily, and keeping up with routine cleanings and exams in Houston helps extend the life of any restoration. Habits like grinding teeth, biting ice, or chewing on hard objects can shorten how long a filling holds up. If you grind at night, a night guard may be worth discussing.

Frequently Asked Questions

**Does getting a filling hurt?** The procedure itself should not hurt. Local anesthetic numbs the tooth and surrounding tissue before any work begins. Some people feel pressure or vibration during the process, but sharp pain is not expected. If you feel discomfort while the dentist is working, let them know and more anesthetic can be added.

**How long does a dental filling last?** Composite resin fillings typically last anywhere from 7 to 15 years depending on the size of the filling, where it is in the mouth, and how well the tooth is maintained. Regular exams allow your dentist to catch any wear or damage early before a filling needs to be replaced.

**Can a cavity go away without a filling?** Very early enamel demineralization can sometimes be reversed with fluoride treatment and improved oral hygiene before it becomes a true cavity. Once decay has broken through the enamel surface and created a hole, however, it will not heal on its own — a filling is needed to stop it from progressing.

**What if I wait to get a filling?** Decay does not stay the same size. A small cavity that could be resolved with a straightforward filling will continue to grow if left untreated. Depending on how far it spreads, the eventual treatment could be a larger filling, a crown, a root canal, or in severe cases, an extraction. Treating decay early is consistently the simpler path.

**Will a tooth-colored filling look natural?** Yes. Composite resin is shade-matched to blend with your surrounding tooth structure. On most teeth, a well-placed composite filling is not noticeable to someone looking at your smile.
