It is a fair question, and we hear it often: if my dentist can put on braces or offer aligners, why would I see an orthodontist? Both are trusted dental professionals, and a good dentist is worth their weight in gold. The honest answer is about training and focus. An orthodontist is a dentist who then spent several more years training in one thing only: moving teeth and correcting bites safely and predictably. Here is what that difference means for you.

The short version

Every orthodontist is a dentist first. Not every dentist is an orthodontist. After dental school, an orthodontist completes around three more years of full-time university training to become a registered specialist. So a dentist looks after your overall oral health, and a specialist orthodontist focuses entirely on straightening teeth and fixing how they bite together.

For a simple case, either may be able to help. For anything involving the bite, growth, complex movements or a nervous first-timer, the extra training is exactly what you are paying for.

What a dentist does

Your dentist is your first port of call for overall oral health. Check-ups, cleaning, fillings, crowns, gum health, and spotting problems early, that is their world, and a great dentist keeps your whole mouth healthy for life. Many dentists also offer some tooth straightening, often clear aligners for milder cases, and for the right patient that can work well.

Dentists and orthodontists are on the same team. In fact, dentists regularly refer patients to us for specialist treatment, and we work alongside them throughout. You can see how that referral relationship works on our page for dentists.

What a specialist orthodontist does

An orthodontist does one thing, all day, every day: diagnose and correct the position of teeth and jaws. That includes crowding, gaps, deep bites, open bites, crossbites, protruding teeth, and guiding jaw growth in children. It is not just about how the teeth look at the end. It is about how they meet, how they function, and whether the result will stay healthy and stable for years.

Dr Shaz MacAvoy, who leads Milk Orthodontics, is a registered specialist orthodontist with four university qualifications, registered in New Zealand and the United Kingdom, and a published researcher. She has trained other clinicians and examined orthodontic auxiliaries for the New Zealand Association of Orthodontists. You can read her full background on our team page. That depth of training is the whole point of a specialist.

Does it actually matter which one I see?

Sometimes it genuinely does not, and we will always tell you so. For a small, straightforward case, a good dentist offering aligners may do a lovely job, and we would never pretend otherwise.

Where the specialist difference matters most is when the case is more than cosmetic: a bite that does not meet properly, teeth that need significant guiding, a child whose jaw is still growing, teeth stuck under the gum, or a complex plan where the wrong move is hard to undo. This is also where a specialist is trained to see problems before they start. If you are not sure which camp your case falls into, that is exactly what a first assessment is for.

Can a dentist do braces and Invisalign?

Some do, yes. Braces and clear aligners are tools, and a dentist is legally able to use them. The question is not can they, but should they for your particular case. Aligner brands market heavily to dentists, so plenty offer them. What a specialist adds is the diagnosis behind the appliance: knowing when aligners will work, when they will not, and what to do when a case does not go to plan. On brands, a quick note of honesty: we used Invisalign in the past and now primarily plan our aligner treatment with Angel Aligners, which we cover on our Invisalign page and our clear aligners page.

Do I need a referral from my dentist?

No. You can book directly with us, no dentist referral needed. Many of our patients come to us on a friend's recommendation or straight from a Google search. If you do have a dentist, that is great, and we are happy to keep them in the loop, but you do not need their permission to get a specialist opinion.

What about the cost?

Specialist treatment is not always more expensive than treatment at a general dentist, because the biggest driver of cost is how complex the case is and how long it takes, not the sign on the door. At Milk, fees are all-inclusive and quoted in writing before anything starts. Simple and cosmetic treatment starts from $7,900 and comprehensive specialist treatment from $9,900, covering records, appliances, all appointments, retainers and aftercare. Interest-free payment plans work out around $60 to $76 a week for most families, and we are a Southern Cross Affiliated Provider. Full details are on our prices page, and if you have a quote from elsewhere and want a second view, we are always happy to give a specialist second opinion.

How to decide

The simplest next step is a free Smile Assessment with a specialist. We look at your teeth, tell you honestly whether treatment is even needed, and explain your options in plain language, including when a dentist could do the job just as well. There is no obligation, and no referral required. You leave knowing exactly where you stand.

Common questions

Is an orthodontist better than a dentist?

Neither is better. They do different jobs. A dentist looks after your overall oral health, and a specialist orthodontist focuses only on straightening teeth and correcting bites. For anything beyond a simple case, the orthodontist's extra training is what you are paying for.

How much more training does an orthodontist have?

An orthodontist is a dentist who has completed roughly three more years of full-time university training to become a registered specialist, on top of a dental degree.

Can my dentist refer me to Milk Orthodontics?

Yes, dentists refer to us often, and we work alongside them. But you do not need a referral. You can book directly.

Should I see a dentist or an orthodontist for my child?

Keep seeing your dentist for regular check-ups. For a first orthodontic check, a specialist is ideal, and we like to see children around the age of seven. Most need nothing done yet, but it is the best time to catch the few problems that are simpler to guide early.

Do I need a referral to see a specialist orthodontist in New Zealand?

No. In New Zealand you can book directly with a specialist orthodontist without a referral.
