Get a free Oral-B ProfessionalCare 5500 rechargeable toothbrush worth £34.99 when you purchase Tesco Dental Insurance.
Cover starts from £8.95 a month and covers you for upto £200 for routine work and £2000 from non routine work. It includes worldwide cover, mouth cancer and dental emergency cover.
Possible Quidco and Clubcard points could also be had.
The best bit about this deal is that unlike most dental insurance policies they don't require you to go for a checkup before qualifying for cover, as long as you wait out the qualifying period (1 month for NHS) and (3 months for Private) you can qualify for re-embursment of treatment. So even if your like me and haven't been for ages if you can find an NHS dentist then after 30 days you can go get treatment and submit you claim.
You pay extra if you go for the premium cover which covers private and NHS costs.
Also you can claim immediately for emergency cover there is no qualifiying period for this.
As with all these types of deals this is not financial advice, do your own research and check the small print but this seems a good deal for me.
