Interproximal Brush 

Interproximal brushes are used to clean the space in between your teeth, like floss. The brushes come in various sizes, ranging from .4 mm to .8 mm. Sometimes referred to as “in-betweeners” these brushes specialize in cleaning wide or open spaces between teeth, including the space around and between the premolars and molars. 

How to Use Interproximal Brushes

3. Move the brush back and forth between the teeth

Interproximal Decay and Cavities

Interproximal decay occurs when the space between two teeth begins to decay. Interproximal decay is hard to identify through general clinical practice and is often found during an x-ray of the teeth. The other way to predict an interproximal cavity is when the decay breaks through the second layer of enamel and wears into the dentin, causing hot/cold sensitivity. 

Because your toothbrush cannot reach the interproximal space of your teeth, it is important to use tools, such as floss or an interproximal brush to clean in between your teeth. This, along with regular brushing and dentist visits will be the best way to avoid an interproximal cavity.
