It's understandable why many people think that since children's teeth can continuously shift while they're growing. However, you should send your kids to the orthodontist as early as seven years of age, or even earlier depending on the circumstances.
If you're located in Sacramento, you should see the orthodontist in Sacramento even if the child is at an early age. You can find out what kind of problems he or she may potentially face in the future.
This gives you an understanding of what the situation is and what kind of treatments that your child can undergo to avoid more serious problems later. Here are some examples of kids that received treatment at an early age.
The child wore a face mask for several months and followed up with a retainer to keep the teeth in place. Undergoing this process shifted the teeth is an aesthetically pleasing manner and allowed the child to eliminate the need of getting braces later on.
The child had severe spacing in the front top teeth. Because the child was at such a young age, the teeth aligned in place in a matter of a year. After the partial braces were taken off, it was followed up by regular use of a retainer to keep the teeth in place and allow the other teeth to slowly adjust to the alignment.
