annoying dental ulcer I used to get a dental ulcer repeatedly ，it is really excruciating . It is a handful when I ate something , but, it wasn't lethal anyway ,so I ignore it and waited for my mouth to get recovered naturally at first . However , things didn't go as I expected . It actually could be cured , but the next relapse also followed it .Each time I cured of it , it occured to me again . I seemed to be unable to get rid of it . I was frustrated and began to pay attention to my diet , lesser spicy food was in my meals . I can't remember eaxctly how long I insist on it , but I still don't eat too much spicy food . A good diet can take some effects , but it's not enough , dental ulcer come now and then . I wanted to overcome it from the foot ,so I searched for the remedy on the internet .Most of suggestions are eating more vegetables and no spicy food . And I got that I likely to lack of vetamins . I bought a bottle of vitamin c tablet and toothpaste which can prevent from dental ulcer ( this function was writed on its cover) . And now , thanks to those multiple measures , though I don't know which one cures me substantially ,It seems like I have got rid of it .
