Q. I have noticed a sulphur or rotten egg smell in my mouth since I got veneers. I am having dental cleanings every 3 months and practice good oral hygiene at home. I didn’t have this problem before the veneers what can I do? I am told that the veneers can not be removed altogether but can be replaced without 100% guarantee that the smell will go away. I now have a great smile but the trade off was not worth it. I’m devestated!,
