Fillings are applied by a dentist to treat cavities and preserve your natural teeth where possible.
– A basic filling replaces a small cavity that is only causing minor pain and sensitivity and hasn’t reached the nerve.
– If a basic filling is not sufficient to repair the damage, a root canal procedure will be required.
– Root canals are used to treat large painful cavities, for example where the tooth is cracked or died (and become discoloured).
“Your dentist can talk about what filling material would suit you best.”
