Remineralization: Early Decay Doesn’t Always Mean a Filling
One of the most important things we teach our patients is that tooth decay is a process — not simply a hole that suddenly appears.
Before a cavity actually breaks through the surface of the tooth, enamel breaks down through the loss of minerals (calcium and phosphate). This early stage is called demineralization. If we identify it soon enough, there are situations where we can shift the environment in the opposite direction and encourage remineralization instead of immediately drilling the tooth.
At Meetinghouse Dental Care, we look at why the tooth is breaking down in the first place.
That can include:
🦷 Plaque and food debris remaining on the teeth
🦠 Acid produced by cavity-causing bacteria
💧 Saliva quantity and quality
🥛 Availability of minerals such as calcium and phosphate
🌱 Oral-care products designed to support remineralization
🍽️ Diet, meal frequency, and the oral environment between meals
We are particularly interested in hydroxyapatite-based products, because hydroxyapatite is the mineral that naturally makes up most of tooth enamel. Depending on the individual situation, other remineralizing therapies may also be appropriate.
The important distinction is this: remineralization works best before the tooth structure has physically collapsed. Once a cavity has progressed through the enamel into a true hole in the dentin or substantial structural damage, the tooth generally needs to be restored.
That is one reason we believe in identifying changes early, understanding the biology behind them, and preserving as much healthy tooth structure as possible.
The best dentistry isn't always about fixing more teeth. Sometimes it's about preventing a tooth from ever needing to be fixed.
