If the gum tissue feels rougher and it is painful it's likely that the gum tissue that covers your alveolar bone has been irritated or injured. This can happen from overly hot or spicy food, injury from eating something sharp or hard (such as a tortilla chip), or possibly a minor bacterial or fungal issue. The roughness may be the injured or healing tissue. But, based on your description, if there is no noticeable swelling or discoloration, this is not likely a serious issue.
If there is no swelling the pain and underlying cause should heal on it's own within ten days. If swelling arises, the pain increases or persists beyond ten days it would be wise to seek an in office exam with your dentist.
For gum irritation there are two simple procedures that you can do at home which are often helpful :
1. Rinsing with a cup or warm water with a teaspoon of salt dissolved in it.
2 Getting some 3% Hydrogen peroxide solution (in the brown bottle) at the drugstore. Mixing the solution 1 part Hydrogen Peroxide with 3 parts water. Rinsing the affected area for about twenty seconds periodically over the next day. This can significantly reduce inflammation if it is present.
Ibuprophen (Advil) is effective for reducing not only pain, but inflammation of gum tissue also (Unlike Tylenol, which is not an anti-inflammatory).
