At home dentists

I think you need to contact your GP, or his existing dentist, to get a referral to the NHS Community Dental Service. They have mobile equipment, and will treat housebound people. It’s an excellent service, the dentists are fully qualified, and specialise in treating people with various disabilities who can’t access normal dental services.

Ring his dentist and ask him what is available
