What Is Dental Fillings?
A dental filling repairs a tooth affected by a cavity or minor damage. Dr. Zhang removes the decayed portion, cleans the area, and fills it with a durable tooth-colored composite that restores the tooth's strength and shape. Because the material is matched to your natural teeth, the filling blends in beautifully, protecting your tooth while keeping your smile looking natural.

How long do dental fillings last?
With good oral care, tooth-colored fillings can last many years. Their lifespan depends on the size of the filling and how well you care for your teeth, and we check your fillings at every routine visit.
Does getting a filling hurt?
No. We numb the area before treatment, so you should feel little to no discomfort during the procedure. Some mild sensitivity afterward is normal and usually fades within a day or two.
Are tooth-colored fillings better than metal ones?
Tooth-colored composite fillings blend in with your natural teeth and bond directly to the tooth, which lets us preserve more of the healthy structure. Most patients prefer them for both their appearance and their conservative approach.
Should you replace old metal fillings in Fullerton, CA?
If you have older silver-colored amalgam fillings, you may be wondering whether to swap them for tooth-colored ones. In most cases, a metal filling that’s still intact and doing its job doesn’t need to be replaced. Replacement is usually recommended when a filling is cracked, worn, leaking, or has new decay forming around it—or simply if you’d prefer a more natural look. The team at Fullerton Smile Dentistry can evaluate your existing fillings and help you decide whether replacing them makes sense for you.
Why is your tooth sensitive after a filling?
Some sensitivity after getting a filling is common and usually temporary. The tooth and nerve can be slightly irritated from the procedure, especially with deeper fillings, leading to brief sensitivity to hot, cold, or pressure. This typically settles within a few days to a couple of weeks. If your bite feels “high” or uneven, a quick adjustment can resolve it. Should sensitivity be sharp, worsen, or linger beyond a couple of weeks, reach out to Fullerton Smile Dentistry so we can take a closer look.
Can a dental filling fall out?
Yes, although it’s not especially common, a filling can loosen or fall out over time. This may happen due to new decay forming around it, normal wear, biting down on something hard, or the bond gradually weakening. If a filling comes out, save it if you can, avoid chewing on that side, and keep the area clean. Contact Fullerton Smile Dentistry promptly so the tooth can be repaired before bacteria reach the exposed area and cause further decay or sensitivity.
How much does dental fillings in Fullerton, CA cost?
The cost of dental fillings depends on a few factors, including the scope of your treatment plan and whether additional imaging or procedures are needed. During your visit, we'll walk you through a clear, itemized estimate before anything begins — no surprises. At Fullerton Smile Dentistry, we work closely with most insurance providers to maximize your benefits, and we offer flexible financing options and new patient specials to make quality care comfortable for every budget.
