I think ive got gingivitis as ive got 2 lose teeth, gums completely covered by plaque and also swelling and redness and bare skin starting to appear, wheezing with breathing problems as well as numbness and swelling of my lips. Ive contacted my dentist twice, but because of the coronavirus pandemic, my dentist will only see those who have severe toothache. What can i do to see my dentist as i need treatment urgently?
