We all love a tooth fairy visit, but isn't it a little weird that we are essentially born toothless, that a set of teeth grow up when we're babies, and lose them to make way for our own. comparatively giant adult teeth?The vast majority of mammals have two pairs of teeth during their lifetime.Our young are born toothless because mammals produce milk for their young, and mothers certainly don't want to be breastfed babies with rows of sharp teeth.Losing our baby teeth -; also called baby teeth because they fall from our heads like autumn leaves -; allows us to change our diet as we age, and makes the most of the food-crushing capacity of our growing jaws.
So what happens when we have our primary teeth when we are babies, but our adult teeth don't come into play? Do we keep our baby teeth forever?
There are a few different conditions that could cause someone not to lose their primary teeth, and dentists have their own way of treating each of them, depending on whether the permanent teeth are waiting for the trainer to put them in or 'they don't make it to the game.
When baby teeth leave the nest
It is difficult to predict how long a baby tooth will last because they are only supposed to do their job for ten years, plus or minus two years. Having said that, if a permanent tooth doesn't take its place, a primary tooth can outlast its lifespan, or it can simply fail completely without warning. When a primary tooth is functioning well past its expiration date, the dentist will likely keep an eye on it to make sure it's healthy, but eventually it will need to be removed and replaced.
If the permanent teeth are taking a little longer to develop than normal, or are sitting in the wings, but they are only just emerging, the dentist will usually want to wait to see what will happen. In the case of an ectopic tooth, a permanent tooth grows normally, but does not erupt. In these cases, the position and angle of the tooth relative to the permanent teeth that have already erupted will help the dentist or orthodontist decide what to do. Often, an attempt is made to orthodontically drag a recalcitrant tooth into the correct position.
But, having perfectly formed permanent teeth that are just a bit slow to emerge is definitely an ideal scenario. It is much more difficult to treat a patient who does not have adult teeth to extract.
Tooth agenesis is a congenital condition in which a patient's mouth was not given instructions to make some of their permanent teeth when they were born.This can range from hypodontia, where five or less teeth are missing, to oligodontia, where six or more permanent teeth are missing in action; this is rare, but, often associated with genetic syndromes such as Down syndrome, Van Der Woude syndrome, Reiger syndrome and ectodermal dysplasia.Anodontia is a rare recessive genetic disorder in which someone does not have permanent teeth and is often associated with conditions like ectodermal dysplasia.
“Congenitally missing teeth are relatively rare,” “In primary dentition, up to 2 % of children will have missing teeth, but in permanent dentition the gap in various studies is 0.15 to 16 %. The most common missing permanent teeth are the lateral incisors and premolars, and it is very common for a missing baby tooth to not have a permanent successor either.
Miracles of modern dentistry
So let's say you don't have some of your permanent teeth. What can your dentist do about it?
A lot of it depends on what's wrong, but you can bet it's probably going to be expensive and time consuming. In the case of a single missing tooth, your dentist can offer solutions ranging from a dental implant to some kind of fixed bridge. One treatment often used for children with missing congenital incisors is to use orthodontics to either open up space for a future implant or bridge or to drive another permanent tooth into the space to camouflage the space.
In the case of multiple missing teeth (depending on their location), patients could end up with implants, fixed bridges or removable partial dentures. But in the event of complete loss of teeth, treatment would consist of removable or fixed prostheses, depending on the degree of bone development around the missing teeth.
Sometimes a dentist will do bone grafts to fill in an area where bone has not developed. But, while dentists can do all kinds of touch-ups, bypasses and screwdriving in the jawbone, any treatment for dental agenesis will need to be continued on an ongoing basis. For a young child with oligodontia or anodontia, this can be a lifelong burden requiring multiple partial or complete dentures until sufficient physical development to undergo implantation.
