Broken Tooth Pain

Life is full of surprises so we'll ensure you get dental care when you need it the most. Our team is here to assist with sudden pain, swelling, inflammation, chipped or broken teeth and lost fillings. Your initial assessment can even be done virtually.

Our Services

The health and safety of you and your family is our top priority, as it always has been. We strongly believe in our responsibility to provide you with our best professional opinion, including a thorough discussion of all options to help create a personalized treatment plan - while recognizing we always need to proceed at a pace you are most comfortable with.


Our goal is to preserve your teeth and their supporting structures from disease and deterioration. Professional dental cleanings are performed by our highly experienced registered dental hygienists and includes the removal of tartar and plaque, teeth polishing, a safe fluoride treatment and an examination by Dr. Missy D'Souza. We also screen for any signs of disease including oral cancer.


Teeth whitening, crowns, bridges, bonding and veneers. Change the colour, size, shape, and alignment of teeth. Fill in unattractive spaces, improve or correct bites, lighten or brighten the colour of teeth, repair decayed, broken, cracked or chipped teeth, replace missing teeth or old unattractive dental treatments. Our team will customize a treatment plan that will make you feel and look good.


Dental implants have quickly become the gold standard for the replacement of missing teeth. The multistage procedure will see an artificial root made of titanium inserted into the jawbone. An artificial tooth (crown) is then attached. Implant treatment is highly successful and produces attractive natural looking teeth with excellent chewing ability.

Sport, Sleep Guard

Protect your teeth from contact activities. Protect your teeth from grinding. Treat snoring and dry throat to get a better night's sleep. We will take great care to create a custom mouth guard for all your sporting or sleeping needs.

Dr. Missy D'Souza

Dr. Mi Seong D'Souza, better known to everyone as Missy, knew she wanted to be a dentist at 3 years old! With a warm and gentle personality, she puts even the most apprehensive patient at ease. Born in Daegu, South Korea, Missy grew up in Sudbury, Ontario. She has a Doctor of Dental Surgery degree from Dalhousie University and an Honours Bachelor of Science degree in Biochemistry from Laurentian University. During her academic years, Missy was awarded 3 prestigious grants to conduct research at the University of Toronto. Her work on the biodegradation of dental composites, or “white fillings” was presented at the leading forum for dental research – The International Association for Dental Research General Session. She is also an author of 2 papers in the scientific literature.

Missy is a loving mom to 3 boys including twins. Her husband, Francis D'Souza, grew up in Clarkson, is a former Citytv news anchor and the current Managing Editor of CBC's "The National".

Missy is a familiar face around Clarkson and Lorne Park. You may have seen her in the local rinks where her boys play hockey or at Birchwood Park where they play baseball. Missy proudly supports the Peel Children's Aid Foundation through the annual presentation of the D'Souza Family Bursary to support the post-secondary education of a child in care and is a member of the caring and sharing group at St. Christopher's on Clarkson Road.
