Dental braces aren't just for adolescents and teens.

An increasing number of adults are choosing braces to straighten their teeth. 

1. Metal braces

The most inexpensive type of braces for adults are the traditional, stainless steel versions. Obviously, the drawback to wearing these is how visible they are. Metal braces hold a thin wire in place with rubber bands to put pressure on the teeth and move them to the desired place.

Metal braces can irritate gums and cheeks at first. Once you have them on, you have to watch what you eat, avoiding things that can stick to the braces, such as caramel or gum. You also have to avoid eating hard foods, which can move or dislodge the braces.

2. Lingual braces

Lingual braces are customized to bond and hide behind the teeth to remain out of sight. They cost more than metal or ceramic braces because the process is more complicated. They require a skillful orthodontist to install them, and not every orthodontist knows how to do it.

Lingual braces don't work well on small teeth and get in the way of the tongue, potentially causing speech problems and injuries, so you have to learn and practice speaking with them on.

3. Ceramic braces

Ceramic braces cost more than stainless steel versions, but they're made to blend in with the teeth so they aren't as visible. You can choose between clear elastic ties or white metal ties to hold the braces in place.

Though the braces themselves won't stain, the ties can easily discolor, especially if you consume foods or drinks that typically stain teeth, such as coffee. Your ORTHODONTIST will replace the ties every time he or she adjusts the braces, which is usually every month.

Ceramic braces are more sensitive and can easily break or chip. They require more maintenance and more time to install than metal braces, which increases overall treatment time and cost.

4. Invisible braces

Invisible braces, such as Invisalign, cost more than any other type of braces because they are practically invisible.

These braces work best for people who don't have significant teeth problems. The advantages: they're less noticeable than traditional braces and often require less frequent visits to the dentist.
