What dentists think of DEPPA


“New patients regularly comment that their previous dentist did not do this which instantly makes us stand out as a practice”. Denplan Excel dentist

“It’s easier to suggest preventive plans and gain patient acceptance when the evidence is right there in front of them". Denplan Excel dentist

“In today’s litigious environment, if I have done a DEPPA and have communicated the results to the patient, they can never come back to me and say that they had no idea about their gum disease for example”. Denplan Excel dentist

“DEPPA has proved so successful for us that we have built our practice philosophy around it”. Denplan Excel dentist

What patients think of DEPPA


"I am entirely satisfied with the service I receive from my dentist. It is very reassuring to know that he has carried out such a detailed assessment and made me fully aware of my dental health and any preventative action that could be taken for the future." Felicity, Denplan Excel patient 


"I feel very confident that the DEPPA process is extremely important in keeping a close guard on my oral health. It is not only a necessary process but a convenient one too as it's done during a routine visit." Heather, Denplan Excel patient


“At my check-up this morning my dentist assessed my oral health with the new online tool, DEPPA. There were a lot of questions to answer but once we had finished the report came up really quickly. I found it very well worded so that anybody would be able to read and understand it. The visuals of the red and green were really good and helped me understand the condition my teeth were in and what I needed to do to maintain them. It was nice to know that this is provided for Denplan patients and it gives us a clear idea of what we can do to help ourselves keep dentally fit. I also found it helped me chat with my dentist about my oral health. I think it would be ideal for people who find it uncomfortable talking with their dentists (especially if their teeth weren’t that good). I am pretty good at looking after my teeth but I have the report and will be able to refer to it now and again just to remind myself!” Joanna, Denplan patient


"I found this a delightful experience and it will really help keep me on track with my dental health in-between visits to the dentist and hygienist." Catherine, Denplan Excel patient 


"My dentist was very professional and explained things clearly to me. The DEPPA literature I received helped me understand how to best look after my teeth." Angela, Denplan Excel patient 


"Made me think more about my teeth!" Jerry, Denplan Excel patient
