Tongue

For the last couple days I've been getting little white bumps on my tongue. My mom diagnosed them as canker sores. I've gotten them in the past, but usually only one and they last 2 -4 days max. At the beginning of the week I got one. I figured it would go away soon, so I ignored the pain and tried not to bite at it. Well, by the next morning there was another one and today there is another one. The first one started to go away a bit, but I'm worried I'm only going to get more. My sister told me just to bite them off. I had more sense then to bite them off. The thought disgusted me. They hurt as well. Some are at the tip, while others are off to the side. When I explained this to my mother, she thought it was from my braces. But to me that doesn't make sense. So that's why I resorted to here. I didn't want a doctors visit, and I figured my mom would dismiss the idea of seeing a doctor because she always assumes it's "nothing"...
Help?

Were there any changes to your braces around the time they started to appear?  Its possible maybe the braces are rubbing and causing some sores in the area?  You can also purchase some canker sore medication at your local pharmacy to see if that helps.  If the sores do persist for over a week or more are appearing, I would consider going to your dentist or medical doctor to find out whats wrong.  There are some health conditions which can make people more prone to canker sores or cold sores and it would be good to make sure that isn't the case, but only if it worsens or if more appear.
