 Trustindex verifies that the original source of the review is Google. Had to go to the dentist today and saw Dr Martin. From the start to end of my treatment I felt totally relaxed (I’m odd I’m not scared of dentist just accountants 😂😂) the dentist and nurse were very courteous and kept the mood light. Put my mind at rest for another few year’s hopefully

 Trustindex verifies that the original source of the review is Google. Was sent here from 111, they got me booked in the day after. Great experience, the staff are polite and pleasant, dentist himself was a really nice guy, saved a tooth that I thought was not salvageable, all in all great dentist, great service, would strongly recommend.

 Trustindex verifies that the original source of the review is Google. This place deserves 6 stars if I could give them that. Not only is everyone extremely friendly, but they are also very skilled at what they do.

Last week I had a tooth extraction, and unfortunately I developed a dry socket. Today I went in when they opened and asked if I could get an appointment to have it checked. I was given an appointment just 50 minutes later.

They took an X-ray and confirmed it was dry socket. They explained that they could perform a procedure to remove the affected bone and stitch it back together. I agreed, and the whole process took over an hour, with two dentists and an assistant working on me.

When I went to pay, I was told that everything was free of charge. Honestly, how many places would do that?
Like I said, if I could give them 6 stars, I would.

Thank you for such excellent treatment.
