Tooth Fillings in Downey, CA

What it is

A filling starts with removing the decayed portion of the tooth. Decay is soft, infected tooth structure, and leaving any of it behind would let the cavity keep growing under the filling. Once the tooth is clean, the space is filled with a tooth-colored composite material matched to your shade, shaped to rebuild the natural contours, hardened with a curing light, and polished so your bite feels normal.

The whole thing usually happens in a single visit. Fillings handle small to moderate cavities. When decay is very large, cracks the tooth, or reaches the nerve, a filling is no longer the right fix, and the doctor will tell you honestly whether you need a crown or root canal treatment instead.

Benefits

A filling is the smallest intervention that solves the problem, and smaller is better in dentistry. Every millimeter of healthy tooth you keep matters decades later.

• Stops decay from spreading. Removing the decayed portion now prevents it from reaching the nerve, where the fix becomes a root canal or extraction.
• Restores normal chewing. The rebuilt shape shares biting force the way the original tooth did.
• Blends with your smile. Tooth-colored composite is matched to your tooth, so the repair is hard to spot.
• Usually a single visit. Most fillings are done in under an hour, numbing included.

What to expect

The area is numbed first. You will feel a small pinch from the anesthetic, then the tooth and surrounding gum go numb over the next few minutes. Once you are numb, removing the decay feels like vibration, water spray, and pressure, but not pain. If you ever feel sharpness, raise a hand and the doctor will give more anesthetic.

The composite is placed in layers and hardened with a bright curing light, then shaped and polished. The doctor will have you bite down and ask how it feels. If the bite feels high or uneven, say so. That adjustment takes seconds and prevents a sore tooth later. You will be numb for a couple of hours afterward, so chew carefully until feeling returns.

Some sensitivity to hot and cold for a few days afterward is common and usually fades. Call the office if the bite feels off, if sensitivity worsens instead of improving, or if you have throbbing pain, which can mean the nerve is involved.

Good to know

• Fillings wear over time and eventually need replacement. How long depends on the size of the filling, your bite, and grinding habits.
• Some sensitivity to hot and cold for a few days after is common and usually temporary.
• A filling cannot save a tooth once decay has reached the nerve. The doctor will tell you honestly if a filling is no longer enough.

Risks of not treating it

Decay does not stop on its own. A small cavity becomes a big one, then an infected nerve, then a toothache that needs a root canal or an extraction. Filling it early is the cheapest, simplest, and most comfortable version of this story.
