When we take x-rays, we're looking for several things. First and foremost is decay. X-rays are necessary to check for decay located between teeth that can't be seen with the naked eye. But x-rays don't just help detect hidden cavities, they tell us much more about your teeth.

Extra teeth, missing teeth, teeth that are impacted or that never erupted through the gums are evident on x-rays.

Tartar located below the gumline or bone recession that indicates the presence of periodontal disease may also be apparent.

Signs of TMJ and bone cancer often reveal themselves in x-rays as well.

You don't need x-rays every time you visit our office, but we do like to take them regularly enough to be sure no problems are missed. Whenever you have x-rays, remember that the amount of radiation you receive is extremely low and that precautions are taken to protect you from even that small dosage.

Sealants have been criticized; however, the evidence in favor of using them on children's teeth is overwhelming. Several recent studies testing the effectiveness of sealants have had positive results. One study found that 75 percent of children with sealants on their teeth had no cavities, while only about 33 percent of unsealed teeth were cavity-free.

Having sealants applied is similar to having your children immunized.

Having sealants applied is similar to having your children immunized. Although tooth decay isn't normally life threatening, it certainly does affect your children's health. And since sealants have been shown to prevent decay and the need for restorations, they can be cost-effective.
