There is no need to be anxious or nervous about having any kind of treatment at Evolve Dentistry. Carol Somerville Roberts has been practicing sedation for the past 25 years; she is a member of the Society of the Advancement of Anaesthesia in Dentistry. Her aim is to make every dental experience a pleasant one.

A pain-free injection which makes you feel like you’re asleep, without actually being asleep. You are unconcerned of what is going on around you, but can still follow the dentist’s instructions. Most people have no recollection of the treatment afterwards, making it perfect for anxious or nervous patients.
If you opt to have sedation, you will need to attend a pre-sedation appointment to ensure that you have an escort available to take you home, that you understand the proposed treatment, have your blood pressure checked and sign consent for your treatment. This means that on the day of your treatment, assuming that you are still happy to proceed as planned, we can just get going with your treatment.
On the day of treatment, you must bring an escort with you who will stay with you after your appointment. Because of the drowsiness, you must not drive or operate any machinery until the day after your intravenous sedation. Your escort must be able to drive you home, you cannot take public transport. Most people feel very tired after the treatment so it is advisable to go home and rest. You cannot go back to work and must avoid alcohol for 24 hours before and after your appointment.

🪥 Smile hack: timing your tooth brushing
Did you know that brushing your teeth straight after eating isn’t always the best idea?
In this quick video, Maggie explains why it’s better to wait a little while before brushing. After eating, especially acidic foods and drinks, the enamel on your teeth can be temporarily softened. Brushing too soon can actually cause more wear.
Waiting around 30 minutes gives your saliva time to neutralise the acids and protect your teeth.
Watch Maggie’s smile hack to learn the simple change that can help keep your teeth healthier.

What exactly is a dental crown?
In this video, Carol explains how crowns help restore and protect teeth that have been weakened by cracks, root canal treatment or large fillings.
A crown acts like a protective cap, binding the tooth together and giving it the strength it needs for everyday biting and chewing.
Watch the video to learn when a crown may be recommended and how it helps protect your smile.

Did you know that chewing sugar free gum after eating can actually help protect your teeth? 🍬➡️🦷
In this video, Carol explains why dentists often recommend sugar free gum after meals. Chewing gum stimulates saliva, which helps wash away food particles and neutralise acids that can lead to tooth decay.
It’s not a replacement for brushing, but it can be a helpful extra habit when you’re out and about and can’t brush your teeth straight away.
