What is best treatment for delayed tooth eruption?

Depends: If you are asking about a baby, the best treatment is it wait. If you are asking about someone older, you should see a dentist to make sure the teeth are there and to make sure nothing is stopping them from erupting.

Depends upon age: If we are discussing a baby, wait. The range of ages for tooth eruption is quite large. If an older child, have a panoramic radiograph taken by your dentist or orthodontist to verify presence of all of the teeth. The american association of orthodontists recommends a panoramic radiograph by age 7 to verify presence of teeth. Some kids are early, most are in the middle and some are late.

Individualized: Delayed tooth eruption should best be addressed by coordinated care between your dentist, oral surgeon and orthodontist. The best course of treatment will be individualized for each patient. I wish i could be more helpful. Seeking a second opinion, sometimes can lead to more questions, but may be helpful.

Depends on cause: There can be many reasons for alteration in eruption of baby and/or permanent teeth, and therefore many solutions. When there is one eruption anomaly there are often multiple eruption anomalies. Sometimes observation is best rx, other times intervention is necessary. See pedodontic specialist before age 7, orthodontic specialist once 1st permanent tooth erupts, for the best advice.
