Dental nurses have to be highly trained and very committed. They must undertake a Diploma and undergo continual further training and assessment.

All our nurses are very approachable and have a wealth of experience. This enables them to deliver calm and empathetic reassurance. They can also offer general oral health advice or explain various treatments.

Jane, Amber and Jeanne are the faces (and voices) of St.Oswalds. Their cheerful competence reassures our patients on the phone, welcomes them at the practice.

Of course, their duties go far beyond that. They can explain treatments, find appointments to suit your diary and always offer same day treatments to patients that are in pain.

If there is a matter that is beyond their expertise, they will gladly arrange for a clinically qualified member of staff to call you back.

The dentist was great with my child. They explained everything that they were about to do in a language he could understand, and answered all of his questions to put him at ease.

Needed to get my 90 year old mother an emergency appointment, and they fitted us in next day. Staff were super helpful given her poor mobility and Rachael was great with her, lots of patience and clear explanations. Highly recommended, professional and friendly.

Anna is truly the best Hygenist I have been to - she has an amazing “bedside manner”, and is really compassionate and caring to her patients. She is thorough, whilst still somehow gentle and empathetic at the same time. Just what an anxious patient needs!

Just had a great experience at St. Oswalds with Ed and Jo. He explained everything really clearly and was very kind, professional and understanding. My teeth were quite broken after a fall and they look good as new! Thank you for being able to see me so promptly and doing such a great job!

Rachael and Jo and the reception team were incredible on my recent visit! I don’t understand how people can be scared of dentists after the quality, thorough care I have received! Very happy :)

The care given by Dr Rachael Slocombe and Jo was outstanding, as was the dedication of Jeanne to meet my required dates for further treatment. As a very nervous and long time absent patient I am very happy to recommend this dentist to anyone who has put off their dental care due to fear or anxiety - I'm so grateful to be receiving the care I need and am comfortable with.

I have just completed my Invisalign treatment with Ria - ably assisted by her nurse Liv - and am absolutely delighted with the results; better than I had dared hope!Throughout the whole process Ria has been beyond helpful and gone out of her way to explain all of the steps and keep costs down, where possible.She has been my dentist for over two years now and is always very thorough in her work and it shows in the results. Thanks to her and the whole St Oswald's Team.

Ed is a great dentist, very friendly and kind. He makes you feel very comfortable and gives you lots of time to ask questions. As I have discovered for myself he now provides retainers at a very reasonable price. I would highly recommend St Oswald.

After not visiting the dentist since COVID was very nervous attending my appointment but i had nothing to worry about Ria was truly amazing made me feel so relaxed & comfortable. Even went out of her way to take my tooth out a week earlier than planned due to getting unexpected pain.Cannot recommend Ria & the lovely staff that assisted on both my appointments Olivia & Jodie. Massive Thank You.

As a family we have always had such a good experience with Anne at St Oswalds and she is particularly great with our three young children. I phoned this evening about 25 minutes before they closed as my daughter had a problem with her tooth/gum and they fitted her in at 5pm, even though they close at that time. Dr Mark Coppen saw her and was excellent. He sorted the problem in 10 minutes and didn't charge us for his time. Thank you so much, we really appreciate such an amazing service and have a very happy six year old this evening!

The care shown by Dr Ria and Liv to my disabled mother was outstanding - they were attentive, helpful, and kind. They escorted her down the stairs while I went to bring the car out front as she was feeling dizzy, then carefully walked her across the street to my waiting car. Absolutely exceptional dentistry for sure, but equally as brilliant people. Thank you! We are lucky to have you in the area :)

Ria has been absolutely brilliant with me and my children. She has gone over and above to ensure my son received the treatment he needed which has been a huge relief. I am very glad we found her and wouldn't hesitate to recommend

As a "none patient" I am in awe at the friendly and empathetic reception I received by the lady who answered the phone. In no time I had an appointment and by the end of the following day my tooth had been attended to in the most professional and friendly way possible.I cannot sing their praises highly enough.

I've recently completed a course of treatments with Anne and Her assistant Jodie. After years of having a huge phobia of dentists can I just say How absolutely fantastic they have been at calming my nerves, being gentle and understanding, explaining the treatments and the positives, totally restoring my faith in their hands. The receptionists too are always friendly and helpful. Thank you once again for a very professional and kind service.

Always so nervous going to the dentist, however Ria and Liv couldn’t have made me feel anymore at ease throughout my appointment. Very professional and informative! Thank you both 😃

Having previously had a horrendous experience at my last dentist in Windsor, I have to admit to having not gone to a dentist for nearly 10 years (yes, I know!), and I have not really been able to use the left side of my mouth for quite some time, either!I went into St Oswald’s this week in a lot of pain and saw Rachael very quickly, then had a lengthy procedure with Ria a few days later, to investigate. Was given meds to calm me down and the whole experience was amazing. Completely pain free. Ria was so calm and talked me through it as she went; thanks to Jo too, who was also really great.I have to go back a few times in the next few months to get the work finished, but I am much less nervous about this.24 hours after and I am still completely pain free - in fact I had completely forgotten what having a pain-free mouth feels like! Thanks to them all. A great surgery.

Received treatment for straightening my teeth with Invisalign and some composite bonding to fill in and shape my teeth at the front. Really happy with the results. Ed is a great communicator and listener. He understood what I wanted to achieve, especially with the reshaping of my teeth at the front, which look straight and white yet also have a natural shape and look to them now.

At the age of 75 years I've attended this dentist for 32 years. Their work is FIRST CLASS and I would never change them. Sometimes leading up to my holiday I have had a problem which they have always managed to fix in time and to the highest standard. I cannot fault them.

Anne Steele has been looking after my dental health for over 10 years. She is extremely knowledgeable, helping me through head and neck surgery and driving the very best outcomes for me in the following years. She puts me totally at ease and takes a personal interest in my well-being making my visits a pleasure. The Invisalign she fitted has not only improved the look of my teeth but has significantly improved my ability to chew and bite.I find all the staff very welcoming and the atmosphere is warm, friendly and efficient. I highly recommend St Oswalds.
Kate Powell
18:11 02 May 24
Amazing patient and dental care! St. Oswalds go above and beyond. I phoned at 5pm to see if they could recommend an emergency dentist as my daughter was very distressed by a tooth that would not come out and I was told to come straight in and they would see her. Really impressed and very appreciative - thank you!!

I needed some urgent treatment and was seen very quickly by Alicia Wimpory who was excellent. Her calm and friendly manner put me immediately at ease and I trusted her completely. I had not been to a dentist for over 5 years but I shall use St Oswald’s services regularly, from now.

My husband was in pain for 4 weeks and attended a dentist near our home in Oxford who advised he required two extractions and they wouldn’t be able to see him until the new year. I was recommended Dr Ria Mathew who was able to see my husband within the week, and instantly advised that only the upper right tooth needs to be extracted and performed the extraction during the appointment. My husband saw Ria last Friday (having driven from Oxford to Midhurst) and he has since recovered fully and is in no further pain. We cannot thank Ria enough for seeing him so quickly and being able to identify the issue and taking the necessary action during the appointment! We would highly recommend going to St Oswald Dental Surgery, everyone made my husband feel at ease and it would be a no brainer to go back, regardless of the journey time.Thank you again RiaRishi & Shreena

Fantastic experience! Thank you so much Anne and Jodie for making me feel so comfortable and at ease. This was the first time I have had a filling in years and I slightly nervous. I felt absolutely nothing, it was actually rather relaxing. I would highly recommend Anne to any patients, she is incredibly calm, kind, caring and gentle.

My previous Dentist was amazing, I married him but he has now retired! St Oswolds was recommended to me and although not local it was the best decision to place my dental care in their capable hands. My current course of treatment has proved to be complex, challenging and extensive. I am incredibly impressed by the treatment I have recieved from both Mark and Ed.They go to great lengths to put me at ease, to explain procedures and my various options. The treatment carried out to date has proved highly effective and the best part is that it was completely pain free. I cant recommend them and thier team highly enough.
Dean Wallis
10:36 12 Oct 23
I would definitely recommend St. Oswalds. As a new patient I was seen within 3 hours and within 24 hours they had completed all the work required to resolve the issue.Ria & team were very friendly, professional and reassuring.

I have been a patient at St Oswald's for nearly 30 yrs and as a very nervous patient, I would not go anywhere else. All the staff are friendly and professional and make the experience as painless as possible. The atmosphere is very relaxed and you can even choose you own music to listen to! Can’t recommend them highly enough.

Ed Coppen has made me a fantastic denture, and has helped me resolve several problems. He is the most patient and careful dentist you could wish for! He has also been most helpful with my wife who has several dental difficulties since Radiotherapy. Thank you Ed!

Really poor experience due to miscommunication between St. Oswalds and their dental partners left me feeling blamed for it, months lost unable to complete treatment after two molars were extracted, out of pocket and trust broken. A great shame that they didn't take more care when things went wrong and/ or offer some financial compensation to rebuild trust.

The staff at St Oswalds are fantastic. Mark's incredibly busy schedule meant that I couldn't get an appointment with him to replace my broken filling for a couple of months. When I called a few weeks later in agony, the staff gave up their lunch break to fit me in to sort it out. We also use St Oswalds for our two children and they take great care with our youngest son who is disabled and requires a more gentle approach. Couldn't recommend highly enough and I would never go to another dentist now!
Andrew Lyons
07:51 12 Jun 23
Mark is the best dentist I know! Technically he is superb and can accomplish endodontics better than any so called specialists. He also had incredible patience dealing with my very aged mother in law. Ed has also treated me brilliantly so it must run in the genes. You will not find a better practice in the South East and won’t get ripped off with stupid West End Prices!!!

I have had a great and relieving experience at St Oswald’s Dental Surgery today. Dr Ria Mathew and Dental nurse Liv were very professional and comforting as I experienced my first dental extraction. It was over before I knew it, their comforting words and presence was unmatched to any previous dental experience. Highly recommend their services and professional dental care.
