Dentists could I have some advice please?

[whatshallwedo]

Recently I have noticed that when I speak my last tooth on the bottom right of my jaw hits against my top back tooth above it. This makes talking feel a bit odd and as if I can't speak properly. I have just had a feel and the tooth on the bottom feels as though it is quite a bit higher than the teeth next to it.

I really notice it when I say words with an S in them, for example the word 'says' makes them hit together twice giving an audible sound.

The tooth itself doesn't hurt and I can't feel a wisdom tooth either. I'm not sure whether to make an appointment with my dentist in case they think I'm mad so I thought I'd ask here for advice first please
