Generally speaking, the front teeth of infants will erupt between 6 to 10 months old. However, some babies will have their teeth earlier or later. The reason why your baby still hasn't got his teeth at 14 months of age could be that his teeth tend to erupt later, or it could be due to other factors. Therefore, you should bring your baby to a dentist for an oral check-up to find out the reason.

5. My child has a wide gap between his newly erupted teeth. His newly erupted teeth are flared and cause the gap. Is this normal?
This condition is referred to the "ugly duckling stage". This is only a transitional stage. Under normal circumstances, as the jaw matures and grows and the canines erupt, the incisors will straighten up and the gap will be closed. Meanwhile, no braces are needed.

6. A permanent tooth has grown behind my child's deciduous tooth. Is it necessary to have the deciduous tooth extracted?
This situation is rather common in children during the tooth transition stage. Generally, the deciduous tooth will fall out naturally and the succeeding permanent tooth will erupt into its position.
As the permanent tooth erupts, it will also push the deciduous tooth until it is loosened and eventually falls out. Therefore, there is no need to extract the deciduous tooth pre-maturely. The deciduous tooth is small in size and will not obstruct the alignment of the permanent tooth.

7. There is a gap in between my front teeth and my front teeth are slightly tilted forward. The edge of the teeth is serrated as well. Is an orthodontic treatment necessary? And do I need to have the serrated edge grinded to make it flat?
Having a gap in between teeth and slightly tilted front teeth are very common during tooth transition. The situation will improve when permanent canines erupt. However, you still need to consult your dentist to see if there are other special reasons leading to your situation in order to avoid delayed treatment. Please refer to the sections on "Irregular teeth" and "Orthodontic Treatment" on this website.
