<s>[INST] Once in a very great while, out of boredom, I will stick a mirror in my mouth to check out my maxillary teeth.  Today, I noticed that my #6 appears to have been slightly chipped and now has a thin a brown ring around the edge of the chip, with a white center.  The chip/ring are both visible and above the gumline.  I have no idea when the chip occurred as I haven't had any discomfort at all.  My best guess is that it happened sometime within the past two years as my dentist didn't mention anything during my last visit.  I'm currently unemployed and without dental insurance so I was wondering how urgent this matter is- could it possibly wait until I find a job/insurance, or do I need to see a dentist ASAP? [/INST] Hello,Possibilities include stain, decalcification or decay. It is wise to schedule an exam. Uf decay is present, a simple filling is possible if it is small. Left untreated, it will get larger and risk developing an abscess.Call your dentist to inquire if there are any notes in your chart concerning discoloration on this tooth. I often make notes to monitor changes. Clean the area well. Check the texture. Does it appear soft or rougher than the smooth enamel? Discuus thus with your dentist and this may help you decide if you need to address thus area right away. Preventon is always best!Thank you for your inquiry. </s>
