Are these chipped teeth "okay?" Could they possibly be bonded or something else? (photo)

It is impossible to diagnosis an issue without a full examination.  When you have a chip in your teeth the dentist needs to determine the extent of the damage.  One method is to use the Ellis classification of fractures.  Looking at your photo it appears that the fracture is only in the enamel or Ellis Class 1.  Your fractures are most likely pain free due to the fact you have not fractured completely through the enamel or outer surface of the teeth.  Your statement of being told to "to try and stop" put a smile on my face.  I would of replied "Easier said then done".  If you do not know what you did to cause this fracture then most likely it was caused by excessive teeth grinding at night (Bruxism).  This is an oral parafunctional habit while you sleep and can be treated with a fitted bite splint designed by your dentist.

Now the important info:  How do you fix this issue or should you fix this issue?  Well since you are symptom free clinically you DO NOT NEED TO FIX THESE CHIPPED TEETH.  Now aesthetically if they bother you then you deserve to get them fixed when it makes sense financially.  Two options I would recommend based off the limited information in the photo.  You can do some fillings/bonding on the edge of your front two teeth.  This will last you many years but you need to understand that these front teeth act like knives when you bite into food.  This repair will eventually wear and need to be replaced.  If this chip is only in the enamel layer of your teeth then you can also have Enameloplasty performed.  Enameloplasty is where the shape and length of the tooth is altered to give a more pleasing look.  It is painless procedure if this is truly an Ellis class 1 fracture.  Normally the central incisors are about 2 mm longer then the lateral incisors so I feel that aesthetically Enameloplasty would be a good options.  The disadvantage is you only have so much enamel and if you continue to chip or wear your teeth they will get too short.  If you decide to do the Enameloplasty investigate Bite Split Therapy. 

Thank you for posting your question.  With the limited information you have given it is difficult to give you an accurate answer.  Your picture does not show the rest of your mouth.  Do you recall when the chip happend or how it happened? Do you clench or Grind your teeth?  It may be enough to smooth out the edges.  However, if there is an underlying bite issue then you may continue to chip your teeth.  Find a Pankey trained dentist in your area for a complete evaluation.  Hope that helps!
