5/5

Dr Sanaz and her team are AMAZING. I have been seeing Dr Sanaz and her team for a while now and they are very talented and professional and just really lovely people too. I am extremely grateful to them. They were highly recommend to me and I can highly recommend them also. A lovely professional team. The best and kind too.

From the moment I walked in, I felt completely at ease. The receptionist was incredibly friendly and professional, which immediately made me feel comfortable. I was then warmly greeted by the dentist, Dr Sanaz, who came out personally to introduce herself before taking me into my appointment, a really thoughtful touch. Dr Sanaz was exceptional, very kind, positive, and reassuring throughout the whole process. She fixed my tooth quickly and perfectly, and I couldn’t be happier with the result. Everything was done to a very high standard, and the outcome was flawless. I highly recommend this dental practice and Dr Sanaz to anyone looking for outstanding care.

Dr. Sanaz and Dr. Pedram are honestly the best of the best. I’ve been to many dentists in my life, but no one has ever matched their professionalism, care, and skill. They make you feel comfortable, explain everything clearly, and the results are always perfect. I wouldn’t go anywhere else.

I’ve been coming to this dental practice for over 10 years, and I can honestly say it’s the best decision I’ve ever made for my dental health. The entire team is warm, welcoming, and truly cares about their patients. From routine cleanings to more complex procedures—especially implants—everything has always been handled with the highest level of professionalism and skill. I couldn’t be happier with the care I’ve received and highly recommend this practice to anyone looking for top-quality dental care. What I really appreciate is how clearly they explain every step of the process and make sure I feel comfortable. The office is always spotless, modern, and equipped with the latest technology, which gives me a lot of confidence in the care I receive. After more than a decade, I wouldn’t trust my smile with anyone else. Highly recommend this practice to anyone looking for exceptional dental care!

Thank you to the wonderful Dr. Sanaz. She truly saved me. She examined me, calmed me down, and gave me clear recommendations that eased my worries and solved all of my problems. I’m very grateful for her care.🤍

Losing my front teeth after a nasty running accident felt like losing my confidence, but thanks to Dr. Sanaz, I got more than just rebuilt teeth—I got my irresistible smile back! The care, precision, and expertise were beyond expectations, and the result? Absolutely flawless. I can’t stop grinning! Thank you for restoring not just my teeth, but my confidence too.

We had an exceptional experience at this dental clinic after my son fell and chipped his adult front tooth. He was understandably very traumatised, but the entire team were absolutely wonderful from the moment we arrived. We were seen incredibly quickly — within the hour — which made a huge difference in such a stressful situation. Dr. Sanaz Tehrani was truly outstanding. She was calm, patient, and incredibly kind with my son, taking the time to reassure him and explain everything in a way he could understand. This was our first time at Implant & Perio Clinic and my son is usually very anxious about dental visits, but despite the traumatic circumstances, this turned out to be the best dental appointment he has ever had. He even enjoyed it! I cannot recommend this practice highly enough. The care, compassion, and professionalism were exceptional!

I had such a great experience at Implant Perio Clinic with Sanaz and Pedram! I went to Pedram for a coronectomy, and I was super nervous as I had never had anything done to surgically my teeth before but he was so reassuring — he did an amazing job and made me feel completely comfortable. I also had teeth whitening with the lovely Sanaz, and my teeth look fantastic — bright, healthy, and natural! She’s so kind and really knows her stuff. I even recommended my dad to see her, and he’s really happy with his recent treatment and service too. They’re both such kind, professional, and caring people, and it really shows in their work. Highly recommend them! Thank you guys :)

Friendly and Highly Professional

"I've been going to Dentique for 7 years now and would not even consider going anywhere else! Everyone at Dentique is friendly and highly efficient. They are intent on making your experience of going to the Dentist as pleasant as possible in the circumstances.

I used to dread going to the dentist, but at Dentique I have fillings and implants and I know from experience that I won't have to worry should I need more treatment.

Angie Hall

Very professional

"An excellent service. Rang on Monday and got appointment on Tuesday. I received full treatment on Tuesday afternoon.

Very professional, efficient and reasonably priced.

Wish I’d attended Dentique years ago instead of suffering poor workmanship and a lot of inconvenience elsewhere.

Highly recommended."

Irene Miller

Cleaner Teeth

"I recently had a scale and polish with the Dental Therapist. Having only had a quick NHS scale in the past I couldn't believe how clean my teeth felt after a very thorough (and painless!!) visit to Dentique! I was overall very impressed with everyone at Dentique as I was made to feel welcome and at ease.

Luke Finch

Fantastic Experience

Fantastic experience at Dentique. Great treatment received. I would highly recommend – they listened to me well and looked after me.

Such great staff could, not do enough for me!"

Lynsey O'connor

Happy With My Smile

For someone that has had multiple surgery, years of fixed braces and a long running fear of all things ‘dentist’. Saying that I enjoyed my visit today surprises me more than most.

My experience was relaxed, engaging, informative and more importantly for me, pain free. The environment, staff and results are second to none. I’m happy with my smile again. Thank you!"

Matthew Hendy

Amazing Practice

"Amazing practice, and fantastic knowledge given by the Dentist Peter, when I was having extractions.

Peter was patient and understanding of my requirements.

I am now starting a course of Implants and feel I couldn’t be in better hands."

Ben Cox

Root Canal Treatment

"I am pretty worried when it comes to dentists. Yet I have a lot of cosmetic work that I would like doing. Before I can have my teeth straightened my regular dentist has told me I need two root canal treatments that I have been putting off for two years.

My dentist recommended Angel at Dentique who is a specialist and I’ve had the first RCT now. Angel was brilliant, he explained everything and even used gel to numb my gum before the injection. So I literally didn’t even feel a thing. Highly recommend anyone needing a root canal treatment to come and see Angel."

Anaeka Nathwani

You Will Not Find a Better Clinic

"I have been a patient/client of Dentique for over 2 years. I had braces and ongoing care including whitening and several other treatments. Their service is excellent. You really feel like the doctors and nurses care. They are reasonably priced and the quality is outstanding.

The have access to cutting edge technology and don’t hesitate to use it. Modern and clean environment. Ladies from the reception are lovely. My 7 year old son is also having his check-ups done here and he loves it, especially Angel. You will not find a better clinic!"

Gosia Prazeniak

Best Dental Practice Around

"I cannot fault the great experience I get every time I visit Dentique. The dentist Pieter is very experienced and nothing is too much trouble. I have always got in on the same day and the nurses and Manager are always there to greet me with a smile and a wealth of knowledge.

Best dental practice around. I would not go anywhere else."

Jamie Lewis

A Complete service

"Easily accessible location with ample parking space. Thoroughly professional service. Friendly. Highly trained and very experienced dental and clerical staff. They offer a complete service.Very easy to get appointment that suited my schedule.

I have been looked after by Peter Crouse from the beginning, and 3 years down the line the results far exceeded my expectations."
