Tips and advice on how to deal with mouth ulcers

Ulcers in the mouth can lead to discomfort and even pain, but they are mostly nothing to worry about too much. Once you understand more about mouth ulcers, causes and treatment options there’s no need to worry.

What is a mouth ulcer?

A mouth ulcer is defined as an open sore on the skin inside your mouth (called the mucous membrane). They often form as a reaction to either trauma (biting your cheek, for instance) or internal changes (such as stress and anxiety). The spot will usually be circular or oval, white or grey, and surrounded by a red edge.

Such oral ulcers can vary in both size and duration with the longest healing time lasting a couple of weeks. It is also possible to have more than one at a time, and they will almost always vary in colour, shape, and location. But remember, if your mouth ulcers are very painful or are lasting for over three weeks, see a dentist for further advice.

They are usually found on the inside of your lips, cheeks or tongue, and cannot be passed from one person to another. It is important to remember that most of the time, mouth ulcers are nothing to be concerned about. They may make eating, drinking, and brushing uncomfortable, but they will usually heal on their own. The initial pain that results from having an open sore in your mouth should go away within a couple of days and be completely healed within a week or two.

What are the causes of mouth ulcers?

There are a huge variety of causes for oral ulcers that may apply to you. Some of the most common factors can include:

  • Biting the inside of your mouth
  • Trauma caused by a sharp edge on your tooth or dental fittings, like braces
  • Weakened natural defences of the mouth, due to bacteria imbalance
  • Stress and illness
  • Acidic foods: lemons, oranges, apples, and tomatoes for example
  • Spicy foods: such as curry or chillies
  • Vitamin or mineral deficiencies
  • Some medications: your pharmacist can give you more information
  • Using a toothbrush with hard bristles

How to heal a mouth ulcer?

Although they are common and generally harmless, mouth ulcers can also be painful and worrying. The first step in dealing with them is simply to be more aware of the above factors and make note of any patterns that result in recurring outbreaks. Speak to your doctor or dentist if you have more specific questions or concerns. They will be able to give professional advice that is unique to your medical history and may prescribe special mouth ulcer treatment.

How to prevent mouth ulcers and speed up the healing process?

Even though ulcers in the mouth tend to heal on their own, there are many ways to help speed up the process and alleviate discomfort. The different types of mouth ulcer treatments range from simple self-care remedies to solutions your pharmacist or doctor can recommend.

Solutions for oral ulcers include:

  • Using soft-bristled toothbrushes with small, rounded heads that are designed to be gentle on delicate mouth tissue are a well-known remedy for mouth ulcers.
  • Choosing a mild toothpaste specifically designed for sensitive mouths that doesn’t contain the foaming agent SLS (sodium lauryl sulphate)*, like Zendium.
  • Avoiding spicy and acidic foods.
  • Using a toothpaste that can boost good bacteria in the mouth and improve the microflora balance, like Zendium.
  • Taking over-the-counter painkillers or lozenges with numbing ingredients to help with pain relief.
  • Medicating with prescribed steroids to help reduce pain and swelling. You should consult your doctor or pharmacist before taking any medication and ensure you follow the dosage instructions and avoid mixing medicines.

One of the best ways to fight mouth ulcers is to prevent them from happening in the first place. From reducing your stress levels to avoiding irritation from chewing gum, there are a variety of simple ways to prevent them from appearing. A good oral health routine – using a soft-bristled brush and a gentle toothpaste – and avoiding foods that irritate your mouth can help you to care for your mouth and keep ulcers at bay.

Everyone’s mouth is different, but with a little time and attention, it is possible to better understand how to manage your health and lifestyle in order to find a mouth ulcer treatment that works for you. Zendium does not contain foaming agents, instead it uses mild ingredients that won’t irritate delicate tissue in your mouth.
