Did you wake up one morning with a blister on your gums or inner cheeks? These spots can be painful, but you might be left confused about what caused them and what you can do to relieve them. By identifying the type of sore, you can get closer to a comfortable smile once again. Here’s a short guide to help you understand when you should visit your dentist for help.
What Are the Types of Mouth Sores?
There are several different types of mouth ulcers, so figuring out which one you may have can help you learn whether it’s an urgent situation you need checked. These are a few you should know:
- Canker Sores: These are often the most common type, but they can be painful and appear white or yellow with red edges.
- Oral Thrush: This is a fungal infection that can happen after antibiotic treatment or when your immune system is weakened. If you have this, you may notice red and creamy white mouth patches or sores.
- Cold Sores: These often manifest outside the mouth around the lips in those who have or have had HSV for a while.
- Oral Cancer: Lesions can pop up as red or white mouth ulcers, but they don’t heal on their own. If you have had one persist for two weeks or longer, then telling your dentist may be worth it.
So, What Can Cause Mouth Ulcers?
If you have a mouth sore, then you might be wondering what caused it. There are several reasons, such as:
- Minor tissue injury
- Biting your cheek or tongue
- Wearing braces, a retainer, or another oral appliance
- Using abrasive toothpaste
- Eating acidic foods
- Stress
- Hormonal changes
How Are Mouth Sores Treated?
You might be relieved to hear that mouth sores often heal on their own. They typically go away after about 10 to 14 days, but there are ways you can facilitate this process. You should drink plenty of water, brush and floss consistently, and rinse your mouth with warm saltwater. This can help remove bacteria that can make the issue worse.
However, if you have an ulcer that lasts longer, then you should let your dentist know about it. Having a checkup can ensure it’s nothing to worry about or give you the early treatment you deserve. That way, you get back a comfortable smile you love.
