Is There Anything I Can Do for This Chipped Tooth?

It sounds as though this has really become a problem for you even though the chip is small.  The most conservative treatment would be to try dental bonding.  I would get fitted for a night guard  after the bonding to help protect it against any grinding.  If this comes off a time or two, then I would consider moving toward a laminate porcelain veneer.  These are extremely durable for those teeth that can't manage dental bonding. Hope this helps.  

The chipped tooth could definitely be fixed, with options such as a composite filling or a porcelain veneer. The only problem is that if it is chipping now, a placed restoration could chip also. You could possibly be grinding or clenching your teeth (during the day or even at night) so the teeth are hitting each other abnormally. It might be a good idea that you have your bite evaluated when the tooth is restored, or maybe you can have a night guard made so it would protect your teeth at night.

Please insist your Dentist fix this.  He/she probably did not understand how much it is annoying you.  You have several options: 


Did your Dentist try smoothing the rough area?  Many times patients are not bothered by the chip, but the sensation it causes to their lip and tongue.  This sounds like what you are experiencing- try it and see. 

If that doesn't work, then ask your Dentist to bond that area, or at the worst replace the existing boding with a new one that incorporates the chipped, rough area.  Realize that this is more unpredictable and may fail, as your bite might be off and may even need adjusting if you really want the bonding to last. 

Finally an aggressive option is a veneer or crown, but I would urge you to get a second opinion about the bonding first if you choose to pursue this option. 


Good Luck and Happy New Year.
