Cosmetic Dentistry

Love your smile! If you are unhappy with the color, position, shape, size, or alignment of your teeth please let us know. We want you to have the smile you have always dreamed of!


Better oral health equals better overall health!
There is a strong connection between the two and we know dental phobia can prevent patients from getting the care that they need. Whether it's a check up exam, cleaning or more, sedation dentistry in addition to our patient and understanding team can help with your anxiety and fear.

Restorations (Fillings)

Keep your tooth whole

Dental fillings use restorative materials to repair teeth which have been compromised due to cavities or trauma.


A barrier of protection

Dental sealants, usually applied to the chewing surface of teeth, block decay(cavity)-causing bacteria from entering the grooves of your teeth. Most often, the sealants are applied to the back teeth.


Your mouth: a window to your overall health

Removal of plaque and calculus (tartar) from the teeth above and sometimes below the gum line is critical in preventing Periodontal or gum disease (an infection that affects the gums and eventually jaw bone, which can lead to a loss of gum and teeth). There are two major stages — gingivitis and periodontitis. Gingivitis is the milder and reversible form; periodontal disease is often more severe. In some cases, gum surgery will be required to reverse the effect of the disease.


The closest option to getting your natural tooth or teeth back

Implants are complete replacement of missing teeth. A titanium screw is placed in the bone and after proper healing a crown is placed on top of the implant to provide a new tooth.

Crowns (Caps)

Fit for royalty

If your tooth is damaged but not lost, a crown can be used to restore its shape, appearance and function. You may need a crown if you have a root canal, a large filling in a tooth or a broken tooth.
A crown, also called a cap, is a hollow, artificial tooth used to cover a damaged or decayed tooth. The crown restores the tooth and protects it from further damage. Crowns can also be used to cover a discoloured or misshapen tooth. A tooth that has been fixed with a crown looks and works very much like a natural tooth. Crowns are also placed on top of dental implants.


Bridge the gap

A bridge is a dental restoration that replaces one or more missing teeth. It extends across an area that has no teeth and is typically made up of an artificial tooth fused between 2 crowns. (A crown is a hollow, artificial tooth that fits over a natural tooth or a dental implant). The bridge is held firmly in place by your own teeth on each side of the missing one(s) or by dental implants. A bridge is permanent and cannot be removed.

Root Canal Therapy

Keeping your natural tooth

Root canals treat diseases or abscessed teeth. Once a tooth is injured, cracked or decayed, it is necessary to open the tooth and clean out the infected tissue in the centre. This space is then filled and the opening sealed.


Eliminate the source of infection

A severely damaged tooth may need to be removed. Healthy permanent teeth may also need to be taken out for orthodontic treatment.


Be proud of your smile again

Dentures are removable prosthetic devices replacing lost teeth. There are two types of dentures – partial and full. Full dentures are often referred to as“false teeth”.

Oral Cancer Examinations

At Henley Dental Oral cancer screening is always an important part of a dental examination

Oral cancer starts in the cells of the mouth, tongue or throat. In this exam, your dentist and hygienist will feel for lumps or irregular tissue changes in your neck, head, face, and inside your mouth. Your dentist and hygienist will also look for sores or discolored tissue in your mouth.


Life is better when you’re smiling

Veneers are strong, yet thin pieces of ceramic (porcelain) or resin (white filling) material that are bonded to the teeth. Veneers are used to repair chipped, decayed or stained teeth and may help in closing gaps between teeth.

Teeth Whitening

Pearly whites

Teeth naturally darken with age, however staining may be caused by various foods and beverages such as coffee, tea and berries, some drugs such as tetracycline, smoking, or a trauma to a tooth. There are various teeth whitening options available, including in-office and at-home bleaching.


Feels strong. Looks natural.

Porcelain, zirconia, lithium disilicate, and composite resin are tooth coloured materials that are all metal free and they look and feel completely natural. In addition to being aesthetically pleasing they are also very durable.

IV Sedation

Relief of anxiety

A method of conscious sedation where you will feel relaxed and sleepy throughout the appointment and often have little recollection of it afterwards.

Nitrous Oxide & Oral Sedation

A preferred approach

A method of conscious sedation where you will remain awake throughout your procedure but will be in a deep state of relaxation while at the dentist office. With nitrous oxide sedation adults are even able to drive home after 100% oxygen is administered to wear off the sedative effects.

Who needs sedation?

Sedation dentistry may also be appropriate for people who:

  • Phobia related to going to the dentist
  • Bad experience with a dentist in the past
  • Particularly sensitive oral nerves/teeth
  • Small mouth that becomes sore during dental work
  • Resistance to local anesthetic
  • General anxiety disorder
  • Low pain threshold
  • Have a significant gag reflex
  • Need a large amount of dental work completed

Excellent dentist and great staff. Hygienists and Front Desk Staff make the experience as comfortable as possible. On time and very friendly... Way to Go

Convenient Text Message & Email Reminders

Many of our patients love our new Text Message & Email Reminders service to efficiently confirm your appointments and remind you of your next visit at the dentist.

We will continue to make reminder calls for patients who are a little less tech savy.

Oral Cancer Screening With VELscope® Vx Technology

The VELscope® Vx is a non invasive handheld device that emits a bright blue light which is used to inspect the mouth and tongue by identifying fluorescent patterns: oral cancer cells have different patterns then healthy tissue cells. During the procedure we ensure that your eyes are protected from this light.

Intraoral Camera: See For Yourself

Advantages of IntraOral Cameras:

  • Instant: you can instantly see what we see as we investigate your teeth, and also what we do when we work on them
  • Accurate: we can take a picture of the inside of your mouth for a bigger and better look, and it really helps to track any changes over time
  • Easy referrals or second opinions: if we need to get another opinion from a specialist, we can easily take a photo and email it to them with your permission
  • Memory jogger: we store these images on your dental record to compare back to later – a great way to really track erosion, staining
  • Better planning: together we can discuss the best treatment plan for you as we go – you then decide how to proceed
  • Learn more: it is a great educational tool to show you exactly what is going on in your mouth... rather than our dentists merely trying to describe it to you in words!
