If your gums have started to swell, there are two main causes for it. The first is that you have irritated your gums or accidentally scratched them by eating something that is particularly sharp or abrasive. The second, and most likely, is that you are suffering from an early stage of gum disease. Gingivitis typically makes your gums swell, become red and irritated. This is a warning sign that should lead you to schedule an appointment with our Houston, TX dental office. If you notice this early warning sign and seek treatment, a dental cleaning may be all that is necessary to treat the condition so that your gums can return to good health. Otherwise, the symptoms could become progressively worse.
