1. Bleaching your teeth - can cause them to have a more transparent look to them and it usually goes back if you stop whitening so much.
2. Grinding. A lot of people grind their teeth at night but have no idea they do it. The tops of the back teeth wear into the backside of the top teeth therefore thinning them out. A nightguard would help keep you from wearing into them more if this is the cuase but won't stop you from grinding. There are usually visible wear on the teeth in certain areas your dentist could check for...you coudl also check yourself and see if your teeth look more flat...esp the canines which are normally pretty pointed.
im 16 and also have this. and I went to the orthadontist and he said its nothing to worry about as its normal. but it just means my enamel is thinning and once its lost its lost. he told me to avoid too much citric foods and juices as they do far more damage to enamel than fizzy juices. I forgot to mention to him if whitning would help take away the look of the transparency, well i hope so. I do grind my teeth though at night unfortunatly. well it would be a good idea to talk your worrys over with the dentist and hopefully they can help youuu!
