What is a dental filling?
A dental filling repairs a tooth that's been damaged by a cavity. At our Sonoma, CA office, every dental filling is a tooth-colored composite, shade-matched so no one will notice it but you. Most fillings take just one visit, and you head back to your day with a tooth that's strong and comfortable again.
When a tooth needs a filling
- A cavity found at your checkup or on your X-rays
- A tooth that's sensitive to sweets, hot, or cold
- A small chip or rough spot where food keeps catching
- An old silver filling that's cracked, leaking, or has decay around it
What to expect when getting a filling
- A careful look. Dr. Oliver checks the tooth with digital X-rays read with Overjet AI and shows you exactly what she sees.
- Numbing first. We numb the area with a local anesthetic, so most people feel only a little pressure.
- Removing the decay. We gently clear away the damaged part of the tooth, going at your pace.
- Shaping the filling. We place the composite in layers, shape it to your tooth, and match the shade so it blends in.
- A bite check. Before you leave, we make sure everything feels right when you close.
Mercury-free, tooth-colored composite fillings
We never place silver amalgam. Our fillings are tooth-colored composite, matched to your natural shade so they blend right in. If you have old silver fillings, we'll replace them when they need it, and tell you honestly when they don't. Overjet AI helps us catch cavities early, while the fix can stay small.
Why Sonoma patients don't wait on a cavity
Cavities rarely stay small. Left alone, they grow deeper, and a simple filling can turn into a much bigger repair. Caught very early, some may even qualify for drill-less fillings with no needles at all. When more of the tooth is damaged, a dental onlay or dental crown may protect it better.
Dr. Oliver will show you which fits. Only the treatment you actually need, never more.

Dental filling FAQs
What is a dental filling, and when do I need one?
A filling repairs a tooth that's been damaged by a cavity. We remove the decay and rebuild the tooth with a tooth-colored material, so it's strong and comfortable again. For very early cavities, drill-less fillings may be an option.
Does getting a filling hurt?
No. We numb the area with a local anesthetic before we begin, so most people feel only a little pressure. If you're nervous, just tell us. We'll go at your pace.
How long does a filling take?
Most fillings are done in one visit. We numb the tooth, remove the decay, place the filling, and check your bite before you leave. You're back to your day without a second appointment.
What kind of fillings do you use?
We use tooth-colored composite fillings only. They're mercury-free, so we never place silver amalgam. Composite is matched to your tooth's shade, so your filling blends right in.
Can you replace my old silver fillings?
Yes, when they need it. If an old silver filling is cracked, leaking, or has decay around it, we can replace it with a tooth-colored filling. If it's still sound, we'll tell you honestly, since only the treatment you actually need makes sense.
Filling, onlay, or crown: how do you decide?
Does insurance cover dental fillings?
Most dental plans cover part of a filling. We accept all major insurances and will walk you through your estimate before we start. For any remaining balance, you can pay monthly with Cherry or CareCredit.
