Is it possible to correct an overbite in a 12 week old Yorkie before his adult teeth emerge?

No, it is not possible to correct an overbite in a 12-week-old Yorkie before his adult teeth emerge.

The eruption of adult teeth begins around 4 months of age and ends at about 7-8 months.

If an overbite is present, the most common treatment is braces which can only be used once all the adult teeth have erupted.

In some extreme cases, surgery may be necessary, however, it should only be considered for severe overbites that cause functional problems (e.g., difficulty eating or breathing) and in adult dogs once the skull is fully mature (usually by 12-18 months of age).
