Orthodontic appliances: what types exist, and which one makes sense for you?

Orthodontics

For many people, an aligned smile is a matter of confidence. But orthodontics is far more than aesthetics: the way your teeth meet and relate to your jaws affects chewing, oral hygiene, the jaw joint and even breathing. Choosing the right orthodontic appliance therefore begins long before the appliance itself — it begins with the diagnosis.

Today there are several options, from traditional fixed braces to virtually invisible clear aligners. None is “best” in absolute terms: the right solution depends on your case, your goals and your routine. In this article, we explain the types of orthodontic appliances available and how, at White Clinic, we decide which one makes sense for you.

Orthodontics is health, not just aesthetics

At White Clinic, we see the mouth as part of the whole body. Good dental alignment makes hygiene more effective, lowers the risk of decay and gum disease, and distributes chewing forces more evenly. A balanced bite protects the teeth, muscles and temporomandibular joint — and it shows in overall wellbeing. This is the “inside-out” logic that guides all of our biological dentistry.

It starts with the diagnosis, not the appliance

Before talking about brackets or aligners, we carry out a thorough diagnosis. We use digital records, photographs and 3D imaging where indicated to understand tooth position, the type of malocclusion and the relationship between the jaws. This digital planning lets us simulate tooth movement and preview the outcome before any appliance is placed.

The right treatment starts with understanding the cause, not with choosing the appliance.

The White Clinic approach

True to the Slow Dentistry philosophy, we would rather dedicate time to the diagnosis than rush a solution — because the diagnosis defines the appliance, not the other way around.

What types of orthodontic appliances are there?

Broadly, appliances are either fixed (bonded to the teeth) or removable (such as aligners). Here are the main options:

Metal fixed braces

the classic metal brackets connected by an archwire. They are highly effective across a wide range of cases, including the most complex, and remain the most versatile solution. Self-ligating versions now exist, doing away with elastics and tending to space out appointments.

Aesthetic fixed braces (ceramic or sapphire)

they work like metal braces, but with tooth-coloured or translucent brackets that are far less visible. They combine the effectiveness of fixed braces with greater discretion.

Lingual braces

placed on the inner surface of the teeth, on the tongue side, making them practically invisible to others. This is an option for those who want total discretion while keeping a fixed appliance.

Clear aligners

a sequence of removable, custom-made trays, produced through digital planning, that move the teeth gradually. Being removable, they make hygiene and eating easier and are virtually invisible — the basis of so-called invisible orthodontics. Suitable for many mild to moderate cases (and, increasingly, complex ones), they depend on the discipline of wearing them for the recommended number of hours.

Removable and interceptive appliances (children)

at earlier ages, removable or interceptive appliances can guide jaw growth and create space, taking advantage of the developmental stage. A first orthodontic check-up is recommended at around 6–7 years of age, as part of our pediatric dentistry approach.

Orthodontics for adults: it’s never too late

More and more adults seek orthodontic treatment — for aesthetic reasons, but also for health. Teeth can shift throughout life, and uncorrected bite problems tend to worsen. Discreet options, such as aesthetic braces and clear aligners, make treatment compatible with professional and social life. Age in itself is not an obstacle: what matters is the health of the gums and supporting bone, which we assess case by case.

How we choose the right appliance for you

The choice is always diagnosis-driven, never a fixed package. We weigh several factors:

1. The complexity of the malocclusion. Some cases are resolved well with aligners; others need the control of a fixed appliance.
2. Your goals. Aesthetic, functional, or both.
3. Your lifestyle. Profession, public exposure and discipline to wear removable appliances.
4. Biology and oral health. The condition of the gums, the bone and the teeth themselves.
5. Digital planning. Which lets us show you, from the outset, the expected result and the realistic options.

This way, rather than “selling” an appliance, we design the orthodontic treatment around you.

Frequently asked questions about orthodontic appliances

How long does orthodontic treatment take?

It varies with the complexity of the case. For fixed braces on both arches, the average duration is around two years, and it can be shorter in simple cases. Your dentist estimates the duration in the treatment plan.

Do clear aligners work as well as fixed braces?

In many mild to moderate cases, yes — and increasingly in complex ones. However, they depend on being worn for the recommended number of hours each day. There are situations where fixed braces remain the best option; that is what the diagnosis clarifies.

Is orthodontics painful?

It doesn’t usually hurt, but some discomfort or sensitivity is normal in the first few days after placement or adjustments. It tends to pass quickly.

I’m an adult — is it still worth it?

Yes. There is no age limit for treating your bite and alignment; what counts is the health of the gums and bone, which we assess beforehand.

Will I need to wear a retainer afterwards?

Yes. Once the movement is complete, wearing a retainer is essential to keep the teeth in their new position. It is a normal and important part of treatment.

Are invisible appliances suitable for every case?

Not necessarily. They are excellent for many cases, but suitability depends on the type of malocclusion. Only a diagnosis can tell whether they are the best option for you.
