I blame working night's for years.
Whilst I was eating a sandwich at lunch today I felt, what I thought was a small stone, between my teeth.
Not wanting to carry on I finally managed to pull out object to find out half of my tooth had fallen out.
Luckily it was the rear of a molar.
No pain as yet, Dentist on friday
