Hi, I haven't brushed my teeth for a while ( i know.. ) but i did today and as i brushed my front upper teeth they started to bleed a little and then become very sensitive after couple of seconds it stopped. but when i was finished brushing my teeth i saw two very small holes. just want to know can this develop into something serious, should i visit my dentist or they will heal if i continue brushing daily? , i have inculded a reference photo below not mine but its the same thing but my are whiter and a bit smaller.
Thanks
Thanks
