Dental Sealants in Mississauga

Tooth decay can begin early in life, especially in the deep grooves of molars where brushing is more difficult. At Mississauga Smiles Dentistry, we offer dental sealants in Mississauga to provide long-lasting protection against cavities especially for children and teens. Sealants are a simple, painless treatment that adds a protective barrier over the chewing surfaces of molars, helping to reduce the risk of decay in hard-to-reach areas. This preventive solution is safe, effective, and an important part of long-term oral health care for younger patients.

What Are Dental Sealants?

Dental sealants are thin, protective coatings applied to the back teeth, typically the molars to block food particles and bacteria from settling into the deep grooves. While brushing and flossing are essential, sealants provide an added layer of defense where toothbrush bristles can’t always reach.

At Mississauga Smiles Dentistry, we use fluoride-releasing sealants, which not only seal the surface but also help strengthen the surrounding enamel and reduce the risk of cavity development over time.

Sealants are most effective when applied shortly after molars erupt, but they can also benefit teens with deep or narrow fissures that are prone to trapping plaque.

Many families combine sealant applications with pediatric dental visits, routine cleanings, or check-ups, making it easy to fit into your child’s ongoing preventive care.

Technology That Supports Sealant Application

Though the process of applying dental sealants is quick and non-invasive, we use several technologies to ensure accuracy, effectiveness, and education especially for parents.

Our sealant services include:

  • Digital X-rays to check for early signs of decay before sealing a tooth
  • Intraoral cameras to show parents the surfaces being treated and explain the procedure clearly
  • A curing light to harden the sealant in seconds and ensure a long-lasting bond


With these tools, we can provide a comfortable, child-friendly experience while giving parents confidence in the care their children are receiving.

Who Should Get Dental Sealants?

Sealants are primarily designed to protect permanent molars as they emerge, which is why we recommend them during the early years of dental development. However, they are also beneficial for certain teens based on cavity risk and tooth anatomy.

Ideal candidates include:

  • Children ages 6–14 with newly erupted permanent molars
  • Teenagers who have deep grooves or pits in their molars and are at higher risk for decay
  • Patients who have difficulty maintaining full brushing coverage on back teeth
  • Those who are cavity-prone despite good oral hygiene habits


At Mississauga Smiles Dentistry, we evaluate each child’s risk level and eruption stage to determine the right timing for sealants. These evaluations are often part of ongoing family dentistry care.

How Much Do Dental Sealants Cost?

Dental sealants are a highly cost-effective investment in your child’s oral health especially when compared to the cost of filling cavities.

At Mississauga Smiles Dentistry:

  • The cost per tooth typically ranges from $30 to $60
  • Most insurance plans cover sealants for children, often up to a certain age
  • A custom quote will be provided based on how many teeth require treatment


We’ll review your child’s eligibility and coverage before treatment and explain all costs clearly. There are no hidden fees, just affordable preventive care designed to support a healthy smile.

What to Expect During the Sealant Appointment

Sealant application is fast, safe, and completely non-invasive. Most appointments take less than 30 minutes and can be done during a regular cleaning or exam.

Here’s what happens:

  • Tooth Preparation
    The targeted molars are cleaned and dried thoroughly to ensure a strong bond.

  • Sealant Application
    The fluoride-releasing sealant is painted onto the grooves of the molar. It flows into the pits and is carefully adjusted for coverage.

  • Curing
    A curing light is used to harden the sealant, securing it in place in just a few seconds.

  • Evaluation
    The bite is checked, and parents are shown the results using the intraoral camera.


There’s no drilling, no freezing, and no discomfort. Your child can return to school or activities immediately after the appointment.

Supporting Your Child’s Oral Health Long-Term

Sealants typically last for several years but may wear down over time. During your child’s regular check-ups or cleaning visits, we will inspect the sealants and reapply them if needed.

Sealants work best when combined with:

  • Consistent brushing and flossing at home
  • Twice-yearly professional cleanings
  • Good dietary choices (low in sugar and acidic drinks)
  • Regular fluoride exposure, if recommended


By combining these efforts, you can significantly reduce your child’s lifetime risk of cavities and help them build lifelong habits for oral health.

I couldn’t be happier with my Invisalign journey with Dr. Mohamed at Mississauga Smiles Dentistry! From my very first consultation to my final results, the entire experience has been exceptional. Dr. Mohamed is incredibly patient, knowledgeable, and takes the time to explain every step of the treatment process. He genuinely listens to your concerns, pays close attention to what you want to achieve, and works with you until you’re completely satisfied with the results. I always felt heard, never rushed, and confident that I was in excellent hands. The transformation of my smile exceeded my expectations, and I’m so grateful for the care and attention to detail throughout my treatment. You can tell that Dr. Mohamed truly cares about his patients and takes pride in delivering the best possible outcome. The staff at Mississauga Smiles Dentistry also deserve recognition. They are warm, welcoming, professional, and consistently kind, making every visit a pleasant experience. From booking appointments to checking in, the customer service is absolutely top tier. I honestly don’t think this clinic has enough reviews for the quality of care they provide. If you’re considering Invisalign or any dental treatment, I highly recommend Dr. Mohamed and the entire team at Mississauga Smiles Dentistry. The service, professionalism, and results are outstanding, and I would choose them again without hesitation. Thank you for giving me a smile that I’m truly confident to show off!

I recently finished my Invisalign treatment at this clinic, and I can honestly say it was the best experience I’ve had in almost two years. Dr. Mohamad Khorshid and the whole staff were incredibly friendly, professional, and welcoming. The results blew me away — I’m beyond happy with how everything turned out. Even though I travelled from Niagara Falls to Mississauga, they accommodated my situation and supported me every step of the way. Huge thanks to the Office Manager Karen and Admin team Ruba, Bozena, and the entire team for taking such great care of me. Highly recommended for anyone in the GTA. I can now smile with confidence for the rest of my life 🙂

I had my crown installed today by Dr. Mindy and her assistant, Zoe, and I couldn’t have asked for a better experience! The procedure lasted a little over two hours, but Zoe made me feel comfortable from the very beginning. She walked me through the entire process, offered me a movie with headphones and a remote, and made sure I knew exactly what to expect—including letting me know ahead of time that I’d have a chance to use the washroom during the appointment, which was such a thoughtful touch for a longer procedure. Dr. Mindy was wonderful throughout the treatment and took the time to clearly explain the aftercare and answer all of my questions. Zoe also went over the post-procedure instructions and dietary recommendations to make sure I felt confident going home. As someone with sensitive gums who’s not a fan of freezing injections, I really appreciated how calm, caring, and reassuring they both were. What could have been an intimidating appointment turned into such a relaxed and enjoyable experience. It honestly felt like I came over for a nice chat, watched a movie… and happened to leave with a brand-new crown! Thank you, Dr. Mindy and Zoe, for your professionalism, kindness, and amazing care. You’ve definitely made me your newest “tooth-crowned queen!” 👑🦷 — Bairma

Dr. Ramez Salti did my tooth implant and bone graft, and I was very happy with the care I received. Thank you to the front desk staff for being friendly and helpful, and to Suzan for her support and great organization. My wife, son, daughter, and I all trust this clinic and highly recommend it.

Dr Khorshid and his team are brilliant! I had many treatments done including cleaning, two root canal, crown placing and lots of cavities! And I got Invisalign!! I already had braces when I was 11 but my lower jaw got crowded again. before Dr Khorshif I consulted with 3 other dentists but never felt comfortable and heard! I had a full hour free consultation with Dr Khorshid and all my concerns were heard and answered! The team very caring and professional! I definitely recommend this place!

At Mississauga Smiles, I felt genuinely welcomed from the moment I walked in. The entire team is exceptionally patient, professional, and clearly skilled at what they do. Dr. Muhammad transformed my smile with remarkable care and precision, and I find myself appreciating the results more with each passing day. The process felt seamless, and I was confident throughout that I was in capable hands. While their services are not inexpensive, the quality of care and attention to detail more than justify the cost. Whether paying out of pocket or through insurance, it’s important to be prepared—but the level of service provided is truly top tier. I would confidently recommend Mississauga Smiles to anyone seeking excellent dental care PS: GE

I have visited Mississauga Smiles Dentistry three times this year, and each experience has been wonderful. From the warm greetings of the receptionists who are very friendly and always greet you with a genuine smile to the welcoming ambience of the facility, everything makes you feel comfortable right away. For the past two years, Meena has been my go-to hygienist, and she is incredibly amazing and helpful. She is friendly, makes you feel comfortable at all times, and is very meticulous when it comes to cleaning my teeth and checking my gum condition. She also provides helpful advice that I truly appreciate. I would definitely recommend Mississauga Smiles Dentistry to everyone!

Dr. Mohammad Khorshid is an excellent dentist and clearly cares a lot about his patients from my personal experience. I had the honour to have Invisalign treatment and composite bonding on my front teeth done with him, so now I can smile confidently after such a long time of feeling ashamed of my smile. He does such a wonderful job and I would highly recommend him as he listens carefully to his patients’ needs and concerns. I could say a lot about Dr. Mohammad but I need to mention how all of the staff were extremely friendly with me. Each and every one of them have given me a very positive experience attending the Mississauga Smiles Dentistry dental office.

I had such a great experience with Dr. Mohamad and the entire team at Mississauga Smile Dentistry! From the moment I walked in, everyone was welcoming and professional. Dr. Mohamad is patient, gentle, and takes the time to explain everything clearly — you can tell he genuinely cares about his patients. The clinic is clean, modern, and the staff make you feel completely at ease. I’m so happy with my results and finally look forward to my dental visits now. Highly recommend!

I was nervous going in since I hadn’t been to the dentist in a while, but from the moment I walked in, I felt cared for. Everything was clean and welcoming — even the chair pillows were so soft, which showed me how much they care about the little details. The staff were friendly and never rushed me. From intake to the exam, they listened carefully to all my concerns and explained each step clearly. My hygienist checked in often, reminded me I could raise my hand if I felt uncomfortable, and made me feel at home, like I was talking to a friend. The dentist also took the time to answer my questions and was kind and gentle throughout. I didn’t expect them to have so much technology — TVs in every room, advanced tools, even ways to communicate seamlessly between staff. It gave me a lot of confidence that I was in good hands. Most importantly, it felt like finding a dental home. I’m not someone who likes switching dentists, but after one bad experience at my last office, this was such a relief. I haven’t had procedures done here yet, only an exam, but I already feel positive and confident that they’ll take great care of me. I also appreciate that they accept government insurance — that really makes a difference for accessibility. Highly recommend!
