Staff were all friendly, humble, respectful and task orientated. Not pushy for unneeded or unwanted procedures. Will be back. Thank you for the work you all put in. 🙂

The impeccable and meticulous care of Dr Ng Lay Choo and her team are long heard of in this estate… I consulted Dr Louisa as a second opinion on the option of fixing a tooth crown.

She stood out as a steady hand in this area of orthodontics. Hearing me out patiently and analysing my oral issues. She also offered professional advice to the various options that availed and was not shy pointing out the pros and cons.

I will be back for a follow up in the weeks ahead and am convinced the level of care offered in this clinic befits the reputation of this team
That has served in this estate for more than 4 decades.

1st time here, atmosphere is great. Few oil paintings hanging around the waiting room, gave me time to enjoy them while waiting. Dr. Louisa d Staff are friendly. Her explanation on the procedures clearly, treatment is careful and letting me know any effect may happened before proceeding to perform. This should be a good mentoring from her Dentist mom, whom in the dentistry for almost 40 years.
Cheers and keep up the good work.

This place is great for kids! My 4.5 year old needed his teeth polished, and it was such a pleasant experience. He wasn’t scared at all. He was given silly sunglasses so that the light from the dental chair wouldn’t hurt his eyes and he was so fascinated looking at his teeth being cleaned in his little mirror. Thank you dentists for putting him at ease!

Edit in Dec 2025:
Brought my 2 year old daughter for her first dental visit after the previous good experience with my older child. The dentists managed to get her climb up the dental chair happily and participate in the whole inspection and cleaning process ! I’m so amazed. Very kid-friendly

Trustworthy dentists who care for their patients.
Had a painless scaling and polishing experience despite my intrinsically sensitive teeth.

A great experience! The dental clinic was lovely, and the dentist carefully removed the tartar hidden in my gums. The dental floss was very smooth afterward. The dentist and nurses were all very kind. Thank you Dr. Louisa and nurse Chiayu!

Dr Cassie is really nice and passionate about her job. Great service and cleaning but also passionate about what she does. Very helpful too, tried to find a cheaper alternative for a foreign worker

Two months ago, I was attended to by Dr Ng Lay Choo. She noticed that my gum condition was not in the most healthy state. There were some swelling and periodic bleeding. Two or three of my teeth were shaky. Dr Ng told me she would conduct a "deep cleaning" of the affected teeth and, hopefully, my situation will improve although the outlook may not be that promising.

The entire procedure took about 45 minutes. She was very patient to ensure that I experienced minimal pain throughout the treatment. She told me what I needed to do to clean my teeth after that treatment and to return for a review one month later.

I followed her instructions. There were some discomfort for about two days. Thereafter, I could feel the improvement to my gum condition.

I returned for a review last month. She noticed that my teeth were no longer shaky and my gum condition were very much healthier. I could feel my affected teeth were firmer. She was very pleased with the outcome and I am delighted with her care and treatment plan that yield this positive outcome.

If I had not consulted with Dr Ng and procrastinated, I believe my gum condition would have worsen and a consultation at a specialist surgery is imminent. It will be a costly affair.

Thank you, Dr Ng for your willingness to attend to my condition despite the odds. I appreciate very much your advice and post treatment plan that I should follow to bring about this successful outcome. I am sure many more will be able to benefit from the care you are able to provide.

My teeth were in pretty bad shape, but Dr. Cassic patiently explained what was going on and taught me how to take better care of them. She’s super cheerful and positive — her energy makes the whole clinic feel warm and happy!

Dr. Louisa is amazing too! She’s very gentle and caring, with great skills and a genuine heart for her patients. She took my dental condition seriously and made me feel so comfortable during every visit. Both doctors are wonderful — highly recommend this clinic!🥰🥰
