After interproximal reduction does that mean teeth are more susceptible to cavities? A lot of clients often ask what is interproximal reduction? What are the side effects? Is interproximal reduction linked to cavities?

1. Orthodontics & Interproximal Reduction

What exactly is interproximal reduction? When is it used in orthodontics? Interproximal reduction is used to remove enamel from the surface of the teeth approximately 0.2 – 0.5mm of enamel is removed.

Interproximal reduction is used to create space for tooth movement and is used in mild overcrowding cases. For severely overcrowded teeth interproximal reduction is not an option and space can only be created through teeth extractions.

2. Interproximal reduction is linked to cavities?  

Interproximal reduction is not directly linked to cavities, but you may develop cavities after interproximal reduction due to bad oral hygiene. Plaque can collect more readily on teeth, that have undergone interproximal reduction, therefore oral hygiene and frequent brushing is necessary.

All teeth must be brushed and a orthodontic toothbrush should be used to prevent any plaque build-up and this can reduce the possibility of cavities developing. After removing enamel from the teeth the dentist will smooth and polish the surface and also apply a coat of fluoride. Patients need to adhere to a good oral hygiene routine to prevent cavities developing.
