Meet Saleha Bajwa

I have been Dr Alia's patient for nearly 10 years now, sge always took under consideration my fears and worries and always tried to save my teeth even if it would be difficult to do so. I tried few dentists before but wasn't happy with the approach, eventually I brought my kids with me and my partner and I can't see myself going to someone else. She knows her job very well, very good with kids, patient and always trying to find the best solution possible. I recommend Dr Alia

April G

Very happy with my dentist and my treatment here. The dentist is very patient and kind. He has been treating me for a number of years now, and I am very happy with his expertise and knowledge. Just had a clean and polish and it was fine. Thank you, see you in three months!

Mary Earley

I’ve been going to Dr Alia Johar for a few years now and recently had cosmetic work done . She’s a fabulous dentist and I’ve always had best treatment. I have been to different dentists in the past but my visit to Dr Alia has been life changing. I was very impressed with the professional conduct and the way before and after changes were phenomenal.In one word I would define her as outclass

She is confident now to get dental treatment. Once again thanks to her.

Patty

Dr Alia Johar is an AMAZING dentist, she really helped me get my mouth back to full health after over eight years of avoiding going to the dentist due to a bad former experience. Dr Johar has showed me how a good dental practitioner is supposed to care for their patients, I no longer have panic attacks or fear going into the dental chair anymore because she really takes the time to understand the needs and sometimes fears of the patient and explains everything she's doing in detail and making sure you are happy with every step she takes! She always has a friendly disposition and I have honestly recommended her to soo many family and friends, she's an absolute star, I wouldn't go to anyone else for my Dental needs and you can tell she genuinely cares about her patients.

Nicole Austin

Alia is very professional and provides exceptional care which always exceeds 5stars. I am delighted to have found such a caring, open and honest dentist whose knowledge is very reassuring. I have nothing but confidence in her work and the advice that she provides. I would be more than happy to recommend her, as good a dentist is very hard to find.

A Kinver

Very accommodating with scheduling appointments, my children feel very comfortable coming here. I have had a very positive experience with Dr. Alia, her and her colleague were very calm and friendly, gave honest and clearly explained details and options.

G G

I had a wonderful experience with Dr Alia Johar, she was very considerate and understanding, and listened to all of my concerns and addressed them. I hadn’t been to the dentists for a very long time due to previous bad experiences, but Dr Johar made me feel very comfortable and I now have no worries about visiting her regularly for check ups and cleaning.

Alaan Shukir

I’ve had the best experience with this dentist, she took care of my teeth for years and she always provided me the best experience. I’m welcome with a smile and positive energy. She saved my life by taking care of my smile. For anyone looking for the best smile go to her. You know what they say great smile = great life :)

Ibrahim aw

I recently completed treatment at Thornton Heath Dental and Implant centre and can't recommend them enough. Dr Alia talked me through my options to create a more aesthetic smile & carried out the treatment, which included a veneer, composite bonding and a wire/removable retainer. Dr Alia and her dental staff provided a safe space for me to ask as many questions as I needed, in order for me to decide on the right plan for my desired outcome. Now that I've completed my treatment and seen the results, I just wish I'd done it a lot sooner.

Akbar Khan

The surgery is very welcoming. This is not the first year I have my dentist treatment with doctor Alia Johar. She is a competent and friendly specialist. Very pleasant and trusting in communication. She does her job superbly and I'm always happy with the result. Overall, I had good impressions of this clinic and its stuff

Maria Oliveira De Souza

I had a broken back tooth that needed to be extracted and was not going to be an easy pull. I have terrible anxiety about going to the dentist and the first point of contact was the receptionist who was so lovely and reassuring. My first consultation started with Dr. Khan who was amazing and she gave me different options in terms of being referred to the hospital (as the tooth was very complicated) or being referred to her colleague, Dr. Alia, who specialises in cosmetic dentistry and was basically the equivalent of going to the hospital. As nervous as I was, I opted for Dr. Alia as I needed the tooth out and couldn't wait up to 4 weeks for a hospital appointment. And let me just say how amazing she is. She is kind, patient and put me at ease as soon as I sat in the chair and she is super efficient at what she does. I absolutely hate going to the dentist but this one is the best I have come across. Definitely recommend!

Keisha Gordon

My dentist Dr Alia Johar is the best dentist . recently she took my tooth out and i didn't feel a thing. She has been my dentist for 13 years. She is brilliant. I receive world-class dental care. you have to wait to get an appointment with her as she is the best and She is super busy so advice book in advance

N S

Dr Alia is an exceptional dentist. She is warm, caring and respectful. She goes over and beyond to ensure you are comfortable. In addition to this she is very professional. I have been with this dental practice for many years and would never change to another. The current receptionist and staff are also professional and warm. It is important for people to feel at ease and valued as a service user and I most certainly do.

Carol Thompson

I am writing on behalf of my Mum. She is a nervous patient and had been braving out but suffering over 3 weeks with gum pain. I was unhappy with the quality of care she was receiving previously and I was advised to try Thornton Heath Dental.After reading the reviews, one stood out in regard to tooth extraction and naming Dr Alia, by coincidence my friend uses the same Dentist and urged me to give it a try.Suffice to say, before Christmas, I made an appointment. Dr Alia was kind, pleasant and professional. She provided my mum with temporary medication and booked an appointment for extraction.Today Mum had her tooth extracted in less than 5 minutes. She is recovering nicely and is over the moon at the fantastic treatment Dr Alia and her Assistant provided. She literally said "I trust Dr Alia, she has such a calming influence".Thank you. 😁

Jackie AQ

Dr Alia Johar.Words cannot say how I feel right now after seeing Dr Alia she is a professional. I have had several dentist over the years and I can honestly say I would rate her in the top bracket. I always look forward to seeing her.Thank you very much Dr Alia.Ps reception team are great too!

M Fuller

Dr Alia Johar has always provided me with exceptional dental service over the many years i have attended Thornton Heath Dental Centre since November 1999. The service is very friendly, courteous and seamless. Dr Alia is very professional, provides first rate dental advice, has a nice personality, open to all types of questions and adept at explaining technical dental terms in a clear manner. I always feel welcomed and at ease with my dental requirements. In addition, it is very easy to book a dental appointment by telephone or in-person. The centre is very clean, excellent interior design and uses advanced technology for various dental procedures. Outstanding service! Highly recommend.

Leon Dias

Total coward as a patient but Dr Alia Johar was extremely empathic during my hygiene appointment. She also suggested a jet wash which I've never been offered before and made my teeth look great. Receptionist and dental assistant were also attentive and friendly. We joked that the water spray, dark glasses and summer heat outside made this like a resort spa ... not often said about Thornton Heath! :-)

Vicki Wharton

Dr Alia was absolutely fantastic! She has been my dental Nurse for years and the treatment is always amazing. I had a deep clean appointment today which I was very anxious about and she put me at ease and made it as pain free as possible and was very patient and reassuring. I always dread my dental appointments but I know I will be at ease and in good hands when I have Dr Alia.

tiffani wilson

I had a extraction with Dr Alia Johar last week, and I cannot give her any more credit than she deserves! She was encouraging, thorough, friendly, professional and calm which made me less anxious. I don't want to see her again as it means losing more teeth, but if I could select anyone to extract, it'll be her! Thank you, Thornton Heath Dental!!

Havana J

I recently visited Dr. Alia Johar in Thornton Heath, London, to have two cavities removed, and I couldn’t be happier with the experience. She’s incredibly professional and genuinely cares about her patients.What stood out the most to me is how honest and transparent she is when it comes to her work. You can tell she truly wants the best for your dental health, without ever pushing unnecessary treatments. That kind of honesty is rare and very much appreciated.The clinic is clean and welcoming, and Dr. Johar made me feel at ease throughout the entire procedure. I highly recommend her to anyone looking for a trustworthy and skilled dentist in the area.
