What’s the difference between a dentist and an orthodontist?
Thinking about straightening your teeth or improving your smile, but not sure whether to see a dentist or an orthodontist? You’re not alone. While both play an important role in your dental care, their training and areas of expertise are quite different – and knowing who to turn to can make a big difference.
In this blog, we’ll explain the difference between a dentist and orthodontist, what each of them does, and how to choose the right expert for your smile.
What is a dentist?
A dentist is a healthcare professional trained to care for your teeth, gums and overall oral health. After completing a five-year degree in dentistry, they can diagnose and treat a wide range of dental issues – from tooth decay and gum disease to fillings, crowns, extractions and routine check-ups.
Dentists are your go-to for general dental care, prevention and maintenance. They can also offer cosmetic treatments such as teeth whitening, composite bonding and veneers. Some dentists may have extra training in specific areas, but their primary focus is keeping your mouth happy and healthy.
What is an orthodontist?
An orthodontist is a type of dentist who has completed further specialist training in orthodontics – the field that focuses on straightening teeth and correcting bite issues. After qualifying as a dentist, an orthodontist undertakes an additional three years of full-time postgraduate study, usually leading to a Master’s or Doctorate in Orthodontics.
Orthodontists specialise in aligning teeth and jaws. They treat concerns like crowding, spacing, overbites, underbites and misaligned teeth. They use fixed braces, clear aligners (like Invisalign) and other appliances to help reposition teeth over time.
So, while all orthodontists are dentists, not all dentists are orthodontists.
Orthodontist vs dentist – who should you see?
The orthodontist and dentist difference comes down to their area of expertise. If you’re dealing with general dental issues – like tooth pain, decay or hygiene issues – a dentist is the right person to see. They can help you maintain a healthy smile and offer guidance on daily oral care.
If your concern is about the position of your teeth or your bite, then an orthodontist is better suited. For example, if you’re interested in Invisalign or braces, or you’ve been told you have an overbite or crowding, an orthodontist will have the specialist training to design and oversee your treatment.
At Sensu, we bring both worlds together. Our team includes both general dentists and specialist orthodontists, so we can offer a truly comprehensive approach – whether you need teeth straightening, cosmetic bonding or a complete smile transformation.
Why does the difference matter?
The difference between dentists and orthodontists isn’t just about titles – it’s about training and expertise. Orthodontic treatment is highly specialised and involves careful planning, monitoring and adjustment over time. A fully qualified orthodontist has the knowledge and hands-on experience needed to guide your teeth safely into alignment.
That’s why, if you’re considering braces or clear aligners, it’s worth choosing a practice with a dedicated orthodontic team. It means your treatment will be planned by someone who focuses solely on straightening teeth every day – rather than occasionally, as part of general dentistry.
It’s also worth noting that specialist orthodontists are registered with the General Dental Council (GDC) as orthodontic specialists, so you can check their credentials online for peace of mind.
Can a dentist straighten teeth?
Some general dentists offer teeth straightening, including clear aligners like Invisalign. However, the level of complexity they can treat may be limited compared to an orthodontist. In fact, many complex Invisalign cases are referred to orthodontists due to the additional training and experience needed.
At Sensu, our Invisalign treatments are led by GDC-registered specialist orthodontists. With more than 12,000 smiles transformed, we’re proud to be one of the UK’s leading and most experienced specialist Invisalign providers – helping our patients achieve straighter, healthier smiles with expert care every step of the way.
