Finding a reliable dentist in downtown Montréal should be simple. Whether you need an emergency appointment, a routine cleaning, dental implants, or a smile makeover, Dr Lachance Dental Clinic has been the go-to choice for patients living and working in the heart of the city since 1998. Located directly inside Complexe Desjardins, we are one of the most accessible dental clinics in Montréal — reachable by metro, bus, or on foot from anywhere downtown.
Why choose a downtown Montréal dental clinic?
For anyone who works or lives near the city centre, choosing a dental clinic in downtown Montréal makes every appointment easier. You can schedule a cleaning during your lunch break, stop by before work, or come in on a Saturday without driving across the city. Our central location on Sainte-Catherine Street means:
- Direct access from the Place-des-Arts metro station and the underground city network
- No need for a car — we are walkable from the McGill, UQAM, and Concordia campuses
- Easy to combine with errands, shopping, or work meetings in the same trip
- Free to access from any neighbourhood: Plateau, Rosemont, Verdun, NDG, Côte-des-Neiges, and beyond
Emergency dentist in downtown Montréal — available 7 days a week
Dental emergencies do not wait for convenient moments. A cracked tooth, sudden toothache, lost filling, or swollen jaw can happen on a Sunday evening or in the middle of a holiday. At Dr Lachance, we offer emergency dental care in downtown Montréal every day of the week, including weekends. Same-day appointments are available for urgent situations.
If you are experiencing any of the following, call us immediately at (514) 845-7121:
- Severe or persistent toothache
- Tooth knocked out or broken after trauma
- Lost crown, filling, or dental bridge
- Swelling of the jaw, gums, or face

- Bleeding that does not stop after 20 minutes
Acting quickly in a dental emergency protects your natural teeth and prevents minor problems from becoming costly treatments. Our team is trained to see you fast, relieve your pain, and stabilize your situation on the same visit.
Comprehensive dental services at our downtown clinic
Our dental clinic serves the full range of patient needs — from first-time visitors to long-term family patients. Whether you are looking for a family dentist in Montréal, a cosmetic dentist near downtown, or a specialist in implants or orthodontics, our multidisciplinary team covers it all under one roof.
General and preventive dentistry
Prevention is the most effective dental care. Our hygienists perform thorough professional cleanings to remove tartar buildup and catch early signs of cavities, gum disease, or oral cancer. We recommend checkups every 6 months, though some patients benefit from more frequent visits based on their history.
- Comprehensive dental exams and X-rays
- Professional teeth cleaning (scaling and polishing)
- Cavity detection and tooth-coloured fillings
- Fluoride treatments and dental sealants
- Oral cancer screening
- Personalized at-home care plans
Cosmetic dentistry in downtown Montréal
A confident smile has a real impact on how you feel at work, in social situations, and in photos. Our cosmetic dental services in Montréal are designed to enhance your smile naturally — without looking artificial or overdone.
- Professional teeth whitening — noticeably brighter results in a single visit or with take-home trays
- Dental veneers — thin porcelain shells that correct colour, shape, chips, and minor misalignment
- Dental bonding — a fast, affordable option to repair chips, gaps, and discolouration
- Smile makeovers — customized treatment plans combining multiple cosmetic procedures for a complete transformation

Dental implants — the permanent solution for missing teeth
Dental implants are the gold standard for replacing one or more missing teeth. Unlike removable dentures or bridges, implants integrate directly into your jawbone, providing a stable, natural-looking, and permanent solution. Our implantology team has placed hundreds of implants for Montréal patients with outstanding results.
- Single tooth implants
- Implant-supported bridges for multiple missing teeth
- All-on-4 implants for full arch restoration
- Bone grafting when needed to prepare the site
Most patients are surprised by how comfortable and straightforward the implant process is. We use digital planning tools and precise surgical techniques to maximize outcomes and minimize healing time.
Orthodontics for teens and adults
Straight teeth are healthier teeth — they are easier to clean, put less strain on your jaw, and last longer. Our orthodontic team offers modern alignment options for both teenagers and adults who want a straighter smile without disrupting their daily life.
- Traditional metal braces
- Clear aligners (Invisalign and similar systems)
- Retainers and post-treatment maintenance
Read our full guide on 5 things to know before starting orthodontic treatment to prepare yourself for the process.
Oral surgery
When a tooth cannot be saved, or when preparing for an implant, oral surgery may be required. Our surgical team performs these procedures with precision and care, using local anaesthesia and sedation options to keep you comfortable throughout.
- Simple and surgical tooth extractions
- Wisdom tooth removal
- Bone grafting and sinus lifts
- Gum surgery and gingival recontouring

Our downtown location makes us a natural choice for patients from virtually every part of the island. We regularly care for patients from:

Over 25 years serving Montréal — why patients trust Dr Lachance
Since opening in 1998, our clinic has built its reputation on one principle: patient care comes first. We do not rush consultations, we explain every treatment option clearly, and we never recommend unnecessary procedures. Here is what consistently brings patients back:
- Experienced, multilingual team — we serve patients in English, French, and several other languages
- Modern technology — digital X-rays, intraoral cameras, 3D scanning for implants, and chairside monitors so you see exactly what we see
- Transparent pricing — detailed treatment plans with no surprise charges; we help you understand your insurance coverage before treatment begins
- Flexible scheduling — early mornings, evenings, and weekends available to fit around your work or school schedule
- Comfortable environment — a calm, modern clinic designed to reduce dental anxiety; sedation options available for anxious patients
Dental anxiety? You are not alone
Dental anxiety affects a significant portion of the adult population in Montréal. If fear has been preventing you from getting the care you need, know that our team is experienced in working with nervous patients. We take extra time to explain procedures, let you set the pace, and offer sedation options that make appointments much more manageable — including nitrous oxide (laughing gas) and oral sedation.
Many of our most anxious patients become our most loyal ones once they realize that modern dentistry, done correctly, is far more comfortable than they expected.
