Slightly Uneven Teeth

[Grinewin]

Hello all! It's been a while, but things with my three hams have been smooth sailing for the most part.

My syrian Bertha, however, is starting to show her age a bit. If the shelter was right about her age, she's around three years old now. I took her to the vet in October because she was drinking more and the vet said that she looked in perfect health but it was possible she was in the beginning stages of either renal failure or possibly renal cancer. She said to lower the protein in her diet and to keep an eye on her weight, as losing weight would be a sign that she's becoming more ill.

So I've been giving her health checks more often and tonight I noticed that her top left tooth is just slightly shorter than the right. Maybe a millimeter or two. Is this enough of a discrepancy that a vet/tooth clipping is in order or should I just keep an eye on her teeth to look out for any further malocclusion?

Thanks in advance
