If you are just about to get braces, there are a lot of things that you can do that will make wearing your braces a lot more comfortable on you.
As your mouth gets used to the braces, the inside of your lips and cheeks are going to be sore. They just aren't used to having something on your teeth like that and it can take a little bit of time for them to get used to the feel of the braces. While that is happening, it's possible for sores to form on the inside of your lips and cheeks. However, you can get some dental wax that you can use. You can take a small bit of the wax, warm it up in between your fingers, and then put it on the offending area, That will help to protect any sore areas and keep them from getting worse. You may also want to swish warm salt water around in your mouth, because that can help sores to heal faster and keep them from getting infected. You can find this wax in the same aisle as other dental supplies like toothbrushes and denture supplies. You can also get it from your dentist or orthodontist.
A water-pick or something similar can help to make your braces a lot more comfortable because it can help to get all the stuff out from behind the wires and around your teeth. A regular toothbrush is OK when it comes to braces, but it really just doesn't do as good a job as it could around the braces. They just weren't really designed to handle braces, so they just aren't as efficient as possible. It's the same when it comes to flossing your teeth. The wires of your braces can make it very difficult to adequately floss your teeth, which can cause you to get cavities in between your teeth or allow things to get caught, like small seeds and other bits of food. However, with a water-pick, the stream of water comes out with enough force that it can get in and around your braces really well and it can act like a flosser, keeping all that stuff out of your teeth.
If you are going to have to wear braces, you want to make sure that you are as comfortable as possible. There are various things that you can do that can cause that to happen.
