Finding out your child has a cavity can feel discouraging, but it’s one of the most common things we treat. At Northeast Children’s Dentistry, a pediatric dentist in San Antonio repairs cavities with tooth-colored fillings that match your child’s natural enamel. The visit is usually short, and most children head back to school or play the same day.
Why your child may need a filling
Cavities form when bacteria feed on sugars and leave behind acids that soften enamel. Once that softening becomes an actual hole, the tooth can’t grow back what it’s lost. A filling seals the damaged area, stops the decay from spreading and lets the tooth do its job again.
Baby teeth deserve the same care as adult ones. They help your child chew, speak and hold space for permanent teeth, and some molars stay put until the preteen years. Left untreated, a small cavity can grow into the nerve and lead to Pulp Therapy or a crown.
What to expect at a filling appointment
- Getting comfortable. Your child settles into the chair, and you’re welcome to sit nearby. If your child is nervous, we may suggest Nitrous Oxide to help them relax.
- Numbing. We place a flavored gel on the gums first, then use Local Anesthesia to “put the tooth to sleep.” Your child may notice pressure or vibration, but the tooth itself is numb.
- Cleaning out the decay. We gently remove the soft, decayed part of the tooth and keep the healthy structure.
- Filling and shaping. Tooth-colored material is placed in layers, hardened with a special light, then polished and checked against your child’s bite.
Afterward, the lip, cheek or tongue may stay numb for a couple of hours. Keep an eye on your child so they don’t chew on that area, and offer soft foods until the feeling returns.
Why tooth-colored fillings
The material we use bonds directly to the tooth, which lets us keep more of the natural tooth than older approaches. It blends in, so a filling on a front or back tooth is hard to spot when your child smiles. Many parents, especially those planning around a PPO plan, ask about white fillings first; our front office can help you review your benefits before the visit.
When a cavity is too large for a filling to hold, your child’s dentist may recommend one of our Dental Crowns instead. We’ll explain why and show you what we’re seeing on the X-ray.
Keeping new fillings strong
- Brush twice a day with fluoride toothpaste and floss where teeth touch.
- Save sweets and sticky snacks for mealtimes instead of all-day grazing.
- Keep up with checkups every six months, where we can catch new spots early.
- Ask us about Dental Sealants for back teeth that don’t have cavities yet.
Is it safe to fill a cavity in a baby tooth?
Yes. The American Academy of Pediatric Dentistry (AAPD) supports restoring decayed baby teeth to prevent pain and infection. Our dentists choose materials and techniques suited to small teeth and young patients.
Will my child feel the filling being placed?
With numbing in place, most children feel pressure but no pain. We talk your child through each step and pause whenever they need a break.
How long do children’s fillings last?
That depends on the tooth, the size of the cavity and home habits. With good brushing and regular visits, a filling in a baby tooth often lasts until the tooth falls out naturally.
Can a cavity be treated without a filling?
Sometimes. Very early cavities may respond to Curodont™ Repair, Fluoride or Silver Diamine Fluoride. Your child’s dentist will tell you if one of these is a good fit.
