Our team will help you maintain your smile and your health 


The role of a general dentist is to assist patients in maintaining the health of their teeth and gums. This is achieved through supportive guidance, sharing knowledge and consistently providing the best care possible.


At Dean Williamson Dental, we will work closely with you to ensure your teeth and gums are as healthy as they can be. Below are some of the services we offer

Dental Examinations 


At Dean Williamson Dental, you can be assured that when you come to the Mackay Customs House for your next dental visit, you will be in safe hands.


We will take the time to thoroughly, yet gently, examine your head, neck, teeth and gums. We will then go over your dental health with you step by step and explain our findings clearly. We also take clear, high-definition photos of your teeth to show you exactly what is going on and how we can help.

How often should you come for a dental examination?

The time between dental examinations does depend on many factors and may need to change over time. At Dean Williamson Dental, our professional and experienced team will work with you to tailor a personalised plan that suits your dental needs.

Dental Decay


Dental decay (or “caries”) is the process where certain types of bacteria slowly dissolve tooth structure.


The decay process begins when plaque (from food) is not brushed away on a regular basis. Bacteria, formed in this stagnant plaque, starts to dissolve minerals in the tooth.


Once dental decay starts, it progresses quickly. As decay grows within a tooth, you may find that your tooth becomes sensitive to cold or hot or even tender to chew on.

There are a few ways to treat dental decay.


If we catch decay early, we can usually thoroughly clean the affected tooth and apply topical pastes high in fluoride to stop the decay from progressing any further. If the decay has progressed, a filling is a great option.

What is a filing?

A filling is a great way to treat dental decay that has progressed inside a tooth.


Firstly, we need to remove all the decay in the affected tooth, this is done under local anaesthetic (we use The Wand to provide anaesthetic– it is amazing).


After all the decay is removed and we get back to solid, healthy tooth structure, we then need to fill and protect the tooth again.


At Dean Williamson Dental, we use excellent quality, white filling materials that blend seamlessly into your natural tooth. The materials we use also bond onto your existing tooth structure, greatly improving the quality and longevity of the filling.

Sometimes after a filling is completed, a tooth may be a little sensitive to cold or heat while the tooth is settling down. This sensitivity usually only lasts a few days.


To noticeably reduce this after-filling sensitivity, the team at Dean Williamson Dental place medication under fillings. This medication will help calm the tooth down and limit any further future symptoms.

Gum Disease

Gum Disease (or periodontitis) is a bacterial infection that attacks and causes the breakdown of supporting tissues around teeth. 

Gum disease begins as a reversible condition known as gingivitis. Gingivitis is inflammation of gums due to plaque accumulation around teeth. The longer this plaque stays on teeth, the worse the inflammation becomes. 

The good news is, as soon as the plaque is removed (by brushing or a thorough clean by a dentist), the inflammation settles down and gums return to a healthy state in a few days. 

If, however, teeth are left unclean and the inflammation is not treated, gingivitis may progress to periodontitis.


Periodontitis is an irreversible condition that affects bone, periodontal ligaments and other supporting structures of teeth. 

Periodontitis often displays no symptoms in its early stages and progresses slowly over a long period of time. The longer this disease is left untreated, the more damage it can cause. 

How to prevent periodontitis.

Good oral hygiene is vitally important to keep gums healthy. It is imperative to ensure plaque is removed from teeth at least twice a day. This is most easily achieved by using a toothbrush and a fluoridated toothpaste. 

Another great way to prevent gum disease from forming is to see us at Dean Williamson Dental. We will thoroughly clean all plaque and calculus (calcium deposit) from your teeth.


We will also take measurements around your teeth every year. These measurements will allow us to clearly see if gum disease is developing early so we can take action immediately. 

How to treat periodontitis. 

Periodontitis can be difficult to treat in the late stages. Treatment is comprised of cleaning around teeth and underneath gums to remove all traces of plaque and calculus. Medication may also be required in the form of antibiotics. 


For more advanced or uncontrollable cases of periodontitis, it is definitely advisable to see a gum specialist (periodontist).

Cracked Teeth

Like most things, if a tooth is brittle or put under a large amount of stress, it may crack. Cracked teeth are uncomfortable and if left untreated, can cause further problems.


A crack usually forms in a tooth with a very large filling surrounded by weak or thin tooth structure.


It is usually this weak tooth structure that breaks first. A cracked tooth can also be a result of trauma, grinding or clenching.

How do I know if my tooth is cracked?

A small to medium sized crack in a tooth will usually (but not always) cause symptoms. These symptoms are most often extreme sensitivity to cold and pain when chewing on the tooth.

Cold sensitivity is caused from the inner part of the tooth being exposed to the outside world through the crack. Pain when chewing is usually due to the fractured portion of tooth structure moving (or flexing).

How are cracked teeth treated?

Preventing a crack from forming in the first place is best. At Dean Williamson Dental, we always practise minimally invasive dentistry. This means that we will not remove tooth structure that does not need to be removed. Preserving tooth structure helps prevent cracks in the future.


If a crack has already formed, how deep the crack is within the tooth will usually determine what treatment is most appropriate. Treatment usually involves removal of the crack and restoring the tooth with either a filling or a crown.


If the crack has progressed into the nerve of the tooth, it may be necessary to complete a root canal treatment. If the tooth has split all the way down to the root, an extraction may be the only option.

Crown and Bridge

At Dean Williamson Dental our crowns and bridges are made in Queensland by an amazing technician, Adrian Tello. Adrian owns and operates his dental lab, ATR Dental Laboratory. He uses the latest technology and equipment to create beautiful crowns and bridges. 


​The treatment process for both a crown and a bridge are very similar. Both usually require two straight forward appointments spaced a week or two apart.


The team at Dean Williamson Dental have many years of experience with crown and bridge work and will walk you through every step. If you have any questions about the required appointments, we would be more than happy to answer them. 

What is a crown?

A crown is a 360-degree case (or cover) for a tooth. It is made from high quality materials including porcelain, zirconia or gold.


Crowns are a fantastic option to hold together fragile or broken-down teeth. They work extremely well to prevent a tooth from cracking after a root canal treatment.

Why is a crown a great treatment option?

At Dean Williamson Dental, we strongly believe that keeping your own teeth for as long as possible is the best approach to dentistry.


Crowns are a fantastic option to help. They not only provide an amazing cosmetic result but are also extremely strong and durable.


Large metal or resin fillings can put stresses on remaining tooth structure and cause chips or cracks. Crowns will hold a fragile tooth together and help protect further damage.

What is a bridge?

If you have a missing tooth or a space between two teeth, a bridge may be a perfect way to fill this gap with a false tooth that looks real.


Like crowns, bridges are made from very high quality, durable materials. Bridges are fixed in position and look exactly like natural teeth.


Bridges require the support of one or more teeth on either side of a gap. These teeth are what we call “abutments” - they provide anchors for the bridge. Abutment teeth support the false tooth or teeth - called a pontic.

Root Canal Treatment

To understand how a root canal treatment works, it helps a great deal to know about what a tooth is made from.


A tooth is made up of a number of layers. The outer shell is made from a hard substance called enamel – this is what we usually see when we look at teeth. Enamel is white (or translucent) in colour.


Under this enamel, is a softer, more sensitive layer called dentine. Right in the middle of every tooth lies the nerve (or “the pulp”). The nerve is made up of blood vessels and nerve endings that keep the tooth alive. The nerve is enclosed in one or multiple canals that travel down the roots of teeth.

Dental decay, if left untreated, will spread through the enamel, through the dentine and eventually enter into the nerve. Once this occurs, it is extremely easy for bacteria to infect a tooth. A dental infection or abscess may then develop.

Steps involved

To treat this problem, we need to remove all decay in the enamel and dentine and all bacteria from the canals in the centre of the tooth.


This process usually requires a few appointments to thoroughly clean and disinfect the tooth.


After the tooth is free from all bacteria, we seal the canals with a filling and place a crown over the tooth to protect the tooth from any further damage.

Snoring can not only have a significant impact on your health but also affect the health (and temperament) of your sleeping partner. Snoring can affect both males and females at any age and usually results from the lower jaw sliding backwards during sleep and placing pressure on the airway.


At Dean Williamson Dental, we can help you and your partner get a better night's sleep by manufacturing customised splints (called mandibular advancement splints) that help open your airway and reduce snoring.

Once a tooth reaches the end of its life and cannot be restored or is severely infected, Removing the tooth may be the best option.

If you have a broken down or infected tooth, we will thoroughly investigate the cause and explain to you in detail all possible treatment options. If the tooth does require removal, we will ensure the area is completely anaesthetised beforehand. We will be gentle during the procedure and after the tooth is removed, we will take the time to explain how you can care for your gums to guarantee fast and predictable healing.

Extracting teeth is not the end of the road. At Dean Williamson Dental, we will discuss the various options to replace a recently extracted tooth and arrive at a customised plan to ensure that your teeth and gums are as healthy as they can be.
