What a cavity is — and why it never heals on its own
A cavity (also called dental caries or tooth decay) is permanent damage to the hard surface of a tooth. It begins when acid-producing bacteria, fed by sugars and refined carbohydrates, dissolve the mineral in your enamel through a process called demineralization. Once that protective layer is breached, decay advances into the softer dentin beneath — and it moves faster the deeper it goes.
Here is the part most people miss: a cavity does not reverse itself or disappear. Without treatment it only grows, eventually reaching the nerve and causing pain, infection, and far more involved care. The good news is that decay caught early is one of the simplest, most affordable fixes in dentistry — which is exactly why timely cavity treatment in Milpitas matters.
- Early decay is often painless and invisible — only an exam finds it
- Tooth-colored fillings restore strength and blend with your smile
- Treating decay early protects you from root canals and crowns later
Catch it early, and the fix stays small
Where your cavity falls on this timeline decides how simple — and how affordable — treatment is. The goal is always to treat at Stage 1 or 2.
Enamel decay
Acid creates a soft spot on the outer enamel. No pain yet, and often no visible hole — this is the ideal time to act.
Small fillingDentin decay
Decay reaches the softer dentin and progresses faster. Sensitivity to sweet, hot, or cold often begins here.
Filling · inlay/onlayPulp involvement
Bacteria approach the nerve and blood supply. Pain can become sharp or constant, and the tooth needs more than a filling.
Root canal + crownAbscess / loss
Infection spreads beyond the tooth. At this point saving it is difficult and extraction may be the only option.
Extraction riskEvery stage you wait can multiply the cost
The most expensive phrase in dentistry is “it doesn’t hurt yet.” A small cavity treated today is a quick, low-cost filling. The same tooth left for a year can need a root canal and a crown — many times the price, for the same tooth. Regular exams with digital X-rays are the only reliable way to catch decay before it becomes painful and costly — which is why early cavity treatment is always the right call for our Milpitas patients.
Figures describe general national cost patterns for comparison only and are not a quote. Your exact treatment and out-of-pocket cost are confirmed in a written estimate after your exam.
Your cavity treatment, step by step
A straightforward composite filling is usually completed in a single 30–60 minute visit at our Milpitas office. Here is exactly how it goes.
Precise diagnosis
Before anything begins, Dr. Khera confirms the cavity’s location, size, and depth using digital X-rays, Pearl AI analysis, and clinical exam — so treatment is matched to what your tooth actually needs.
A written plan first
You receive an itemized treatment plan with your insurance breakdown and out-of-pocket estimate. We never start care you haven’t reviewed and approved.
Comfortable numbing
We gently numb the area so the procedure is pain-free. Most patients are surprised by how easy a filling actually is.
Remove the decay
Only the decayed portion is removed, and the area is thoroughly cleaned — preserving as much healthy, natural tooth as possible.
Place & shape the filling
Tooth-colored composite is bonded directly to the tooth, then sculpted and cured with an LED light to match your bite and natural shade.
Polish & check the bite
We polish the restoration and fine-tune your bite so it feels seamless. You leave with a fully restored tooth — usually the same day.
Composite fillings vs. old metal amalgam
Our office places tooth-colored composite fillings — chosen for how they look, how they bond, and how much natural tooth they preserve.
When decay affects more than about half the tooth, a bonded filling may not be enough — an inlay, onlay, or dental crown gives better long-term protection. Dr. Khera always recommends the most conservative option that lasts for Milpitas patients.

Frequently asked questions
Common questions about cavities and tooth decay treatment in Milpitas, answered plainly.
Does getting a cavity filled hurt?
For the vast majority of patients, no. We gently numb the area first, so you shouldn’t feel pain during the procedure — most people are surprised by how easy it is. Mild sensitivity for a day or two afterward is normal and usually fades on its own. If a cavity already hurts before treatment, that often means the decay is advanced, which is one more reason not to wait.
How long does a cavity filling take?
A typical composite filling is completed in a single visit of about 30 to 60 minutes, including numbing, removing the decay, placing the filling, and checking your bite. Larger or multiple cavities may take a little longer, and we’ll tell you exactly what to expect before we begin.
How much does cavity treatment cost in Milpitas?
The cost depends on the size and location of the cavity and the filling material. Fillings are considered medically necessary, so most dental insurance plans cover a meaningful share. Before any treatment, you receive a written, itemized estimate with your insurance breakdown and out-of-pocket cost — and we offer financing through Cherry and CareCredit if you’d like to spread payments out.
Can a cavity heal on its own without a filling?
Once decay breaks through the enamel, it cannot reverse or heal itself — it only grows deeper over time. Very early softening of the enamel can sometimes be strengthened with fluoride, but a true cavity needs a filling to stop the decay and restore the tooth. Regular exams let us catch problems at that earliest, most treatable point.
What happens if I leave a cavity untreated?
An untreated cavity keeps spreading. What could have been a simple filling can progress to needing a root canal and crown, and eventually to infection or tooth loss. Each stage you wait generally means more involved, more expensive care — so the most cost-effective choice is almost always to treat decay early.
Do you use metal or mercury fillings?
No. Our office places tooth-colored composite fillings, which contain no mercury and no metal. Composite bonds directly to your tooth, reinforces it, blends with your natural shade, and preserves more healthy tooth structure than old silver amalgam.
How do I know if I have a cavity?
Early cavities are often painless and invisible, which is why exams and digital X-rays matter. Warning signs can include sensitivity to sweet, hot, or cold; a visible dark spot or hole; food catching in one spot; or a dull ache. If you notice any of these, schedule a visit — and even if you don’t, a routine exam is the only reliable way to catch decay early.
My child has a cavity in a baby tooth — does it still need treatment?
Yes. Even though baby teeth eventually fall out, untreated decay can cause pain, infection, and damage to the adult teeth forming underneath. We provide gentle, kid-friendly cavity care designed to keep your child comfortable and protect their developing smile.
