I had 3 vaneers put on my 3 lower middle teeth to close up gaps. My gums have receeded quite a bit so when the vaneers were put on they do not connect to the gum line as the dentist said closing all the gap to the gum line could cause problems with the gums. So the vaneers are joined at the top but have gaps down to the gum line which you can t really see but they feel uncomfortable and sharp and my tounge is constantly going to the gaps. Food is always getting stuck in these gaps as well.
