Floss Dental Collective exceeded my expectations. The staff are very knowledgeable and friendly, taking the time to explain everything throughly and providing gentle and expert care. I’m grateful to have found an exceptional and highly recommend to anyone who is in search of top quality care and a positive experience.

I had a filling done and I did not feel any pain or any tingle when my gum was frozen. Always felt something with my previous dentist .
My tooth was filled very quickly.
Dr. Le has a very gentle hand and is very quick in completing the job.
I can’t say enough nice things about Dr.Le

Five stars for this dental office and hygienist Nell! Friendly, professional, and very detail-oriented. They made my routine cleaning a breeze and the results are fantastic. The best hygienist I’ve ever been to in my 26 years of life!

Have only had positive experiences at Floss with Dr.Le, Sarah, and Nell. The whole team has been super friendly and helpful. They were very patient and thorough and provided excellent care. They also accept the Canadian Dental Care Plan insurance coverage which is an awesome bonus. Thank you!

I’m so happy that I found on the internet this dentistry a couple of months ago.
We had an amazing experience with Dr.Lee and Mrs.Soraya, and I can’t recommend them enough. They were incredibly kind, patient, and understanding with my daughter, who needed help with two teeth but was very anxious and not ready for treatment at first. Despite taking X-rays and spending a lot of time trying to make my daughter comfortable during the first two visits, Dr.Lee did not charge us anything and never made money the priority. What truly stood out was her genuine care and professionalism, she focused on my child’s well-being rather than the fee. It’s rare to find a dentist who shows this level of compassion, especially with children. We are very grateful for their help, honesty, kindness, and dedication. Highly recommended for any parent looking for a dentist they can truly trust.

I have been a client of Floss Dental Collective for many years. All visits with hygienists and dentists have been a good experience. I have had two crowns fitted. Fillings replaced.

My latest visit to have a crown fitted, was with the new owner and dentist, Dr Le. I was impressed with the care and ease of the visit. The latest techniques and equipment were used to give me the best experience possible. I could not be more pleased.

Frequently Asked Questions

Why should I have an assessment?

Oral health for overall health! Regular dental assessments help protect not just your oral health, but also your overall health. For instance, signs and symptoms of some systemic diseases, such as rheumatoid arthritis, lupus, and diabetes, might show up in the mouth first. If your dental hygienist or dentist finds indications of disease, she will suggest that you see your medical doctor.

What Is Debridement?

Debridement is a term used to describe the physical removal of plaque and tartar accumulation during your dental hygiene visit with your dental hygienist. It is important to remove this build-up of bacteria regularly to maintain healthy gums and to prevent gum disease and decay.

What causes cavities?

Caries (cavities) can occur for many different reasons and the risk factors that can contribute include; a high sugar diet, vitamin/mineral deficiencies, poor oral hygiene, dry mouth, insufficient fluoride, drug/alcohol abuse, and gum disease.

What is a Crown or a Bridge?

Crowns and bridges are fixed prosthetic devices that are cemented onto existing teeth or implants. Crowns are used most commonly to entirely cover a damaged tooth or an implant. if you’re missing one or more teeth, bridges can be a good option to replace (bridge) the missing ones.

What is Sedation Dentistry?

Medication is used in sedation dentistry to assist patients unwind while having dental work done. It is particularly beneficial for people who have poor pain thresholds, sensitive teeth, or dental anxiety. The purpose of sedation is to help you feel relaxed and comfortable while the dentist works, not necessarily to put you to sleep.

How a Root Canal can help?

A root canal removes the infected nerve and the root canal system is thoroughly cleaned and sealed to prevent re-infection. This treatment allows you to keep your natural tooth.

Do You Need A Nightguard?

A nightguard is recommended for those with clenching and grinding habits so that your teeth are protected from these movements and forces of this habit.
