If you are over 21 and want to achieve a perfect smile by aligning your teeth, here are the four types of adult dental braces you can consider:
Metal braces
This is the cheapest type of appliance to use for adults. This is the original stainless steel clamp that was the first to hit the market. The great thing about this brace is its low cost. However, it has a drawback, as it is visible. It can also irritate the gums and is easy to peel off, especially when the user eats hard food.
Ceramic braces
This splint is slightly more expensive than the metal one. It is not visible and is held in place by elastic or metal ties. Ceramic appliances don’t have as many drawbacks as their metal cousins. However, they have two known concerns. Your ties stain easily, especially if you consume tooth-staining foods or drinks like coffee. The discoloration of the ties causes the dentist to replace them with new ones each time he visits his clinic.
Ceramic appliances are also sensitive and brittle. They must be handled with care, especially during installation, a factor that drives up their cost.
Lingual braces
This is a type of custom brace. It is installed behind the teeth which makes it invisible. It is more expensive than the metal or ceramic brace because its process is complicated and its installation requires the skilled hands of a skilled orthodontist.
Tongue braces can be ideal for adults because they do not work very well on small teeth. When the brace does not fit the wearer’s teeth properly, it has the potential to get in the way of the tongue. This can cause speech problems and possible injury.
Invisible braces
This is the most expensive type of dental appliance for adults. It is invisible and designed for people without serious dental problems. An invisible brace does not come with braces that mount to the teeth. A lingual brace is fitted with aligners made as the wearer puts on, except when eating or brushing their teeth. Wearing this corset also involves wearing different aligners once every two weeks. This will help move the teeth to eliminate gaps and align them.
These are the adult dental braces and their respective attributes. If you plan to use a dental appliance, the information we have on each of them can serve as a guide to make a decision.
