Dental Care in Leamington, Ontario

At the office of Karen Archer, D.D.S., we offer a range of comprehensive and cosmetic dental services to patients of all ages. Dr. Archer and Dr. Weisshaar have the expertise and knowledge needed to provide every patient with the care they deserve. With a warm and welcoming environment, our patients feel comfortable and can ask any questions they may have about their dental treatment.

Services we offer include, but are not limited to:

Routine Dental Cleaning

It is suggested that patients should be seen for a dental cleaning and routine exam every 6 months or as recommended by your dentist. During the cleaning, plaque and calculus will be removed from your teeth leaving behind a bright and polished smile. X-rays may need to be taken to help detect possible cavities in between teeth that cannot be seen by the naked eye.

Periodontal Services

Though your mouth may feel healthy and you may not have any symptoms, periodontal disease can progress without a patient knowing. If left untreated, periodontal disease can destroy the supporting bones in your mouth. This is why early treatment and prevention is so important! Your dentist will make sure you are receiving the highest quality of care that will assist in preventing periodontal disease from developing.

Digital X-rays

Dental x-rays are a great preventative, diagnostic tool that provides important information not visible during a regular dental exam. Our dental team will utilize this important information to safely and accurately detect any dental abnormalities and then create an accurate treatment plan.

Fluoride Treatment

Dental Care in Leamington, Ontario

Periodically we will suggest a fluoride treatment for your teeth. It's a simple and quick process and can be done during your routine exam. No extra appointment is necessary. Fluoride, a mineral that helps prevent tooth decay, is applied to your teeth. This strengthens the enamel so your smile will be as strong as ever.

Teeth Whitening

Soon after starting treatment at our office for teeth whitening, you will start to see a whiter and brighter smile. With our whitening services, the effects of coffee, smoking, tea, and other causes for tooth discoloration will slowly disappear leaving a beautiful white smile. We also offer take-home whitening systems. Schedule an appointment for a consultation today.


This is an affordable, effective technique for camouflaging crooked or misshapen teeth while preserving your original teeth. By bonding tooth-coloured fillings to your teeth, we can close gaps and hide unsightly stains or chipped teeth. The best part: we don't cut away any of your tooth!


Porcelain veneers are thin, tooth-coloured shells that Dr. Archer uses to improve the appearance of your smile. She will bond the veneers to the surfaces of the teeth to correct certain dental flaws. Your porcelain veneers are customized for a perfect fit and natural appearance. When in place, porcelain veneers can:

  • Close spaces between the teeth
  • Lighten and brighten the teeth
  • Improve the beauty of your smile
  • Repair chips, wear, or cracks in teeth
  • Correct teeth that are misshapen, crooked, or uneven

The procedure usually requires two visits to our office to complete. When your veneers are in place, you can enjoy a radiant new smile. Contact us today for more information on how porcelain veneers and cosmetic dentistry can benefit you.

Composite (Metal-free) and Amalgam Fillings

At this time, both composite and amalgam restorations are available at our office. As technology advances and materials improve, we attempt to use composite or metal-free fillings wherever possible.

Crowns and Bridges

Crowns and Bridges in Leamington, Ontario

Crowns are necessary when a tooth is severely damaged or has suffered from advanced decay and cannot be fixed with bonded filling material. Crowns cover the remaining tooth and restore its function, strength, and esthetics. Several crown material options are available including non-metal crowns. Your dentist will discuss these on an individual basis depending on the area of the mouth that needs to be restored.

Bridges can be utilized when tooth loss occurs due to gum disease, decay, or injury. The loss of the tooth can create greater problems for your dental health if it is not corrected. The teeth next to the missing tooth (or teeth) can begin to move and result in pain, discomfort, and can look unsightly. With bridges, our doctors will close any gaps in your mouth. The bridge looks and acts just like natural teeth, is permanently cemented, and helps to maintain the position of the rest of your teeth.

Endodontic Therapy (Root Canals)

Root canal therapy is needed when a cavity has reached the pulp of a tooth causing an infection of the nerve, or when severe trauma has affected the tooth. Regular checkups with your dentist helps to avoid and prevent the need for endodontic therapy. But once the pulp has become infected, it must be treated to avoid further issues since it cannot heal by itself. Some signs that a pulp is infected include sensitivity to hot or cold foods or liquids, pain, swelling, or even a bad taste in the mouth. For some patients no symptoms are obvious and they are unaware a problem even exists until they are seen by their dentist for an exam.

When endodontic therapy is performed, your dentist will clean out the infected pulp, and disinfect the canals of the tooth. Once the area has been disinfected, the canals of the tooth are filled with a special material to prevent from further infections, and help in the healing of the tooth. Sometimes a core build-up, bonded post, and crown are necessary for restoring a tooth to function.

Dental Implants

Dental implants are a great alternative to traditional bridgework, and dentures. They are safe and look and feel just like natural teeth. Implants are permanently anchored into the patient's jawbone and no preparation of adjacent teeth is required.

It is important to replace missing teeth, because if left with spaces, your teeth can shift and cause a variety of other dental and medical problems. Our office has extensive experience in treatment planning and designing implant solutions that are custom tailored for each individual patient. Implants do require several visits and take months to complete.

Bruxism Guards

Sore jaw muscles on waking and worn teeth (visible with our intra-oral cameras) are signs that you may be clenching or grinding (aka bruxing) in your sleep. To preserve your teeth and joints, we often recommend a bruxing guard.


Are you looking for an alternative to traditional braces? Invisalign® may be the solution for you! The Invisalign® system uses a series of clear plastic aligners to create tooth movement. It is recommended for patients with mild to moderate spacing or crowding. The aligners are virtually undetectable, easy to use, and comfortable to wear.

Karen Archer, D.D.S. is proud to offer patients this convenient teeth straightening system. Contact us today for a free consultation with Invisalign® certified Dr. Whitney Weisshaar.

Dental Emergencies

Dental emergencies can be very frightening and often painful. Prompt treatment is generally required to alleviate pain and ensure the patient's oral and overall health. If you're dealing with a dental emergency, call us immediately at 519-326-3313 and we will schedule you in as soon as possible.

Sodium Diamine Fluoride (SDF)

SDF is an anti-microbial agent used on young children to stop and prevent tooth decay. It is applied on the affected teeth using a small brush. It is a fast and painless intervention to prevent decay from progressing without the use of injections and drills. For best results, application may be recommended every 6-12 months.


Custom sports guards provide the best protection from dental injury and concussions from impact sports. We use superior materials to ensure a perfect fit, comfort and ease of breathing.


Sealants are a thin plastic coating applied onto the chewing surface in order to help prevent cavities from developing in difficult to clean areas.

Sealants help us to prevent cavities in the deep pits and grooves of back teeth known as molars. Molars are rough, uneven and a favorite place for leftover food and cavity-causing bacteria to hide.
