Dental Sealants

What is Dental Sealant

Sealants are a safe and painless way of protecting your children’s teeth from dental decay. A sealant is a protective plastic coating, which is applied to the biting surfaces of the back teeth. The sealant forms a hard shield that keeps food and bacteria from getting into the tiny grooves of the teeth and causing decay.

The grooves and depressions that form the chewing surfaces of the back teeth are extremely difficult (if not impossible) to clean of bacteria and food. As the bacteria reacts with the food, acids form and break down the tooth enamel, causing cavities. Recent studies indicate that 88% of total cavities in American school children are caused this way.

Dental sealants protect these susceptible areas by sealing the grooves and depressions, preventing bacteria and food particles from residing in these areas. Sealant material is a resin typically applied to the back teeth, molars and premolars and areas prone to cavities. It lasts for several years but needs to be checked during regular appointments.

Dental Sealants

At Metro City Dentistry, we offer dental sealants as a simple yet highly effective way to protect your teeth — especially the back molars — from cavities and decay. Sealants are thin, protective coatings applied to the chewing surfaces of the teeth, creating a barrier that blocks out food particles and bacteria. They’re especially helpful for children and teens, but adults with deep grooves in their molars can benefit too.

As part of our general dentistry and preventive care approach, we often recommend sealants alongside dental cleanings, oral exams, and cavity treatment when necessary. If you’re managing early signs of decay or simply want to take extra steps to protect your smile, dental sealants are a smart, painless option. Book your appointment today and help keep your teeth stronger, longer — with preventive care that works.

Implant-Supported Dentures Could Help You Avoid Bone Loss

Not long ago, the most affordable option for total tooth loss was a removable denture. Dentures, prosthetic (false) teeth set in gum-colored acrylic plastic bases, can effectively restore function and appearance. But the appliance continues to have one major drawback: it can accelerate bone loss in the jaw.

Like other living tissues, older bone cells die and become absorbed into the body (resorption). Normally they’re replaced by newer cells. The forces generated when we chew our food travel through the teeth to stimulate this new growth. This stimulus ends when we lose our teeth, and so cell replacement can slow to an abnormal rate. Eventually, this causes bone loss.

Removable dentures can’t provide this stimulation. In fact, the pressure generated as they compress the gums’ bony ridges can even accelerate bone loss. That’s why over time a denture’s fit can become loose and uncomfortable — the bone has shrunk and no longer matches the contours of the dentures.

In recent years, though, a new development has been able to provide greater support to dentures while at the same time slowing or even stopping bone loss. We can now support dentures with dental implants.

Implants are best known as individual tooth replacements: a titanium metal post replaces the root, while a life-like porcelain crown attaches to the post to replace the visible tooth. In addition to providing a longer-lasting alternative to removable dentures, implants provide a very important health benefit: they improve bone density because they mimic the function of natural teeth. Bone cells are naturally attracted to the titanium; they adhere to the titanium post and are stimulated to grow through the action of chewing, increasing bone density and securing the implant’s hold in the jaw.

Using the same technology we can support removable dentures, or even full fixed bridges. Rather than rest directly on the bony ridges, a denture can make a secure connection through a coupling system with just a few strategically placed implants. We can also permanently attach a full bridge by fastening it to a few implants with screws.

Not only do we eliminate the pressure from dentures compressing the gums and bone tissue, we can actually stimulate bone growth with the implants. Although more costly upfront than traditional dentures, unlike traditional dentures which must be replaced every five to seven years, long-lasting implants may be more cost-effective over the long-run.
