Restorations & Fillings

Dental fillings and repairs using restorative materials used to repair teeth which have been compromised due to cavities or trauma.


Dental sealants, usually applied to the chewing surface of teeth, act as a barrier against decay-causing bacteria. Most often, the sealants are applied to the back teeth, e.g., premolars and molars.

Root Canal Therapy

Root canal treatments on diseased 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 center. This space is then filled and the opening sealed.

Crowns & Bridges

Crowns are dental restorations that protect damaged, cracked or broken teeth. Dental crowns often referred to as caps, sit over the entire part of the tooth that lies above the gum line. Crowns are also placed on top of dental implants. Bridges are a method to replace a missing tooth or teeth. Bridges are false teeth anchored in place by neighboring teeth. A bridge consists of two crowns on the anchoring teeth along with the false tooth in the center.


A severely damaged tooth may need to be extracted. Permanent teeth may also need to be removed for orthodontic treatment.


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


Dentures are 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 Examination

Oral cancer starts in the cells of the mouth, tongue or throat. Oral cancer screening is usually a routine part of a dental examination. In this exam, your dentist will feel for lumps or irregular tissue changes in your neck, head, face, and inside your mouth. Your dentist will also look for sores or discolored tissue in your mouth.

Teeth Whitening

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 at-home bleaching. We’ll have you smiling bright at the Heart & Crown in no time.


Veneers are strong, thin pieces of ceramic or resin materials that are bonded to the teeth. Veneers are used to repair chipped, decayed or stained teeth and may help in closing gaps between teeth.

Gum Hygiene Treatments

Periodontal or gum disease is an infection that affects the gums and 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.

IV Sedation

The most powerful method of sedation available in general dentistry. A method of conscious sedation where you will feel relaxed and sleepy throughout the appointment and then have no recollection of it afterwards.

Conscious Sedation

With conscious sedation, you will remain awake throughout your procedure but will be in a deep state of relaxation. It is recommended that patients receiving conscious sedation have a parent, spouse, or friend accompany them to appointments because it can take several hours for the sedative to wear off and driving may be unsafe.


Some conservative treatments that we offer include oral splints or night guards, trigger point injections, and botox.

Sleep Apnea & Snoring Appliances

Snoring may be a sign of a breathing problem called obstructive sleep apnea (OSA). Both can be treated with a simple custom-made oral appliance that is worn at night.

Frequently Asked Questions

How often should I go to the dentist?


We recommend that you come to our office every twelve months for regular checkups unless otherwise recommended by Dr. El-Hawary. At your annual checkup, we’ll perform an examination of your oral health and clean your teeth to make sure they’re completely clear of plaque and bacteria.

Some patients only go to the dentist if they have a problem, but the focus should be on preventative dentistry. Even if you take care of your teeth by brushing and flossing daily, it’s easy to miss areas between teeth and under the gumline. Plaque can harden into a material called tartar, which is nearly impossible to remove on your own. Tartar can buildup and lead to cavities, so it’s crucial to come in for regular cleanings every few months depending on your gum health.

What questions should I ask a new dentist?

Prior to scheduling an appointment with your new dentist, it’s helpful to schedule a consultation so you can get to know the practitioner and see if they’re a good fit. 

Some important questions to ask your new or prospective dentist are:

  • How long have you been in practice?
  • What kind of dental technology do you use?
  • How do you treat patients with dental anxiety?
  • Do you stay up to date with the most recent dental techniques?
  • What kind of emergency care do you provide?
  • What kind of services do you offer?

It’s important that you find a dentist who can meet your needs and address your concerns. You’ll also want to find a dentist that’s close to your preferred location. If you have any questions, feel free to contact our office by calling (613) 406-6464. We’re happy to explain the services we offer.

What is fluoride and why is it important to dental health?

Fluoride is a mineral that fights bacteria and plaque, which eat away at your tooth enamel, thereby preventing cavities. While our bodies naturally make fluoride, it’s also in certain kinds of toothpaste and some mouthwashes. 

Since fluoride helps to protect against cavities, we recommend using dental products that contain fluoride as part of your oral care routine. We also offer professional fluoride treatments that are highly concentrated and only take a few minutes to apply.

Why are x-rays important at the dentist?

Many disorders can’t be seen with the naked eye or are hidden under the gumline. X-rays can detect issues such as:

  • Abscesses or cysts
  • Developmental abnormalities
  • Some types of tumors
  • Decay that exists between teeth or below restorations
  • Infections in the bone or gums 

When we examine your oral health on a regular basis, we’re able to detect any issues before they become complicated and require more intensive treatments. Scheduling regular checkups and professional cleanings at our downtown Ottawa office will help ensure your mouth is free of disease and in the best of health.
