With this trick, Good orthodontist in Hanoi will remove a portion of tooth enamel (ranging from 0.1 to 0.5mm). This amount of tooth enamel is very small and will be slowly removed through each different appointment. Therefore, patients will almost not feel any sensitivity or increased sensitivity when using foods that are too hot/cold.

In some rare cases, where the patient is too sensitive, the doctor will prescribe that each appointment only remove 0.1mm of tooth enamel and use additional anti-sensitivity and enamel-regenerating agents such as fluoride varnish or fluoride gel.

Indications for interdental grinding

In orthodontics, interdental grinding is widely prescribed, especially in the following cases:

  • The 2 front teeth are slightly protruding. The customer wishes to improve aesthetics and adjust the tooth axis.
  • Slight crooked upper or lower jaw. Interdental grinding is indicated in cases where crowding is less than 4mm, the patient is not at risk of tooth decay and the tooth enamel is still strong.
  • Size difference between upper and lower teeth. When analyzing jaw samples, doctors will pay attention to the Bolton index (ratio of lower teeth/upper teeth). At the end of treatment, in order to achieve an ideal overbite, overbite, and good chewing, intercuspation is required.
  • Interdental grinding combined with tooth extraction or distalization to increase the possibility of reducing overbite or underbite.
  • The patient wants to reduce the size of the incisors to improve aesthetics because the incisors are too large.
  • Abnormal tooth shape, teeth have a triangular shape (tooth neck is small, tooth crown and biting edge are large), black triangles often appear in the tooth neck area. To make these triangles smaller and improve the aesthetics of the wedding bud, doctors often reduce the size of the middle 1/3 and the biting edge 1/3 by interdental grinding.
