At All Smiles Bethesda, we strive to help you keep your natural teeth healthy and beautiful for a lifetime. We offer several preventive care services that aim to protect and fortify your smile.

Oral Cancer Screenings

Our office is not only dedicated to your smile, we’re also dedicated to your overall wellness. We take a holistic approach to your dental care, which includes an oral cancer screening as a part of your regular exam. Like many kinds of cancer, oral cancer can be life-threatening if not diagnosed and treated early.

Fluoride Varnish

For most of our patients, we recommend a professional Fluoride application as part of your regular cleaning visit. Application of Fluoride varnish only takes a few minutes and can last up to 6 months, which can help prevent decay and improve tooth sensitivity. Ask us if you are a good candidate for Fluoride application.


Dental Sealants are plastic resins that are placed in the hard to reach pit and fissure regions of your tooth. They give your teeth extra protection against decay and help prevent cavities.

Composite Fillings

All Smiles Bethesda, we take a holistic approach to dentistry. We are an Amalgam-Free office which means we do not use silver fillings that can release mercury and cause staining. We have partnered with 3M to provide you with the highest composite resin materials that are both esthetic and durable.
