Cavities Q & A

What is a cavity?

A cavity is a small hole in your tooth that grows over time when left untreated. It’s most often caused by tooth decay due to a buildup of plaque and bacteria. Plaque is a sticky film that clings to your teeth, creating acids that eat away at your enamel. This leaves your teeth unprotected against harmful bacteria.

Cavities are often viewed as a common dental concern in children, though adults with poor oral hygiene habits or a diet high in sugar are also at risk of developing cavities.

How do I know if I have a cavity?

Many people experience no cavity symptoms at all, but the most common warning signs include:

  • Tooth pain
  • Tooth sensitivity
  • Pain while chewing
  • Visible holes in your teeth
  • White, black, or brown tooth stains
  • Sharp pain when drinking something hot or cold


You may have no idea a cavity is forming until it has already damaged your healthy teeth, which is why it’s important to schedule routine dental cleanings with Dr. O’Mallon at least once every six months.

What are my cavity treatment options?

If you think you have a cavity, Dr. O’Mallon will inspect your smile for any signs of tooth decay. During this exam, he will most likely take X-rays to determine if the damage has spread beyond one tooth.

Next, Dr. O’Mallon will fit you for a filling, a dental restoration that seals the hole in your tooth and protects it against further damage. There are many different types of fillings to choose from at Dr. O’Mallon’s office, including:

Microabrasian Dentistry

A minimally invasive technique used to gently remove decay. It uses a fine stream of air and fine particles of medical grade aluminum oxide. No "drilling" needed.


Composite fillings

Composite fillings are tooth-colored to blend in with the rest of your smile. They are made from materials like plastic, which bond to your tooth and create seamless results. Composite fillings are more expensive than amalgam fillings, and often do not last as long. However, they require less tooth preparation.


Porcelain or ceramic fillings look and feel exactly like the rest of your teeth. While more expensive than alternative options, they stain less than composite fillings and are considered to be the most aesthetically pleasing type of filling.

Glass Ionomer

Made from acrylic and glass powders, glass ionomer fillings are translucent and inexpensive, making them an ideal option for patients looking for a seamless filling that blends in well with their smile. They also release small amounts of fluoride over time to prevent future tooth decay.

Laser Dentistry

A dental laser is designed to specifically for oral surgery or dentistry. This allows the removal of soft tissue procedures with little or no bleeding, therefore avoiding the need for sutures.
