My partener and myself are presenting the same symptoms of scalloping tongue , should i be worried? this is a kind of transmited infection? i had a blood test with all negative regarding any std, its not painful, there is no change of colour.

Scalloping tongue: Scalloping tongue also known as crenated tongue results from tongue pressing against the teeth. It is not a disease. Crenated tongue is usually asymptomatic and harmless. It may also be seen with bruxism (grinding of teeth). No connection to STDs or STIs.

Here are some...: How long have you observed "scalloping tongue"? If for months to years with no change in color and extent, it is likely harmless and deserve a just watch and see since in fact it results from compression of tongue against the adjacent teeth; hence, it is not a disease. More? Seek local professional evaluation because it is hard to say something at 100% accuracy without a direct look at. Best wish
