What Is Causing My Bad Breath?


At Smile Hub Dental Clinic in Bayside Medical Centre we know that poor oral health can cause bad breath. When bacteria are allowed to build up in your mouth they produce toxins which result in bad breath. Long-term persistent bad breath can result in periodontal or gum disease. Strongly flavoured foods such as onions can also lead to bad breath along with smoking and drinking alcohol. Some patients who are suffering with an infection or illness can have bad breath.  Certain medications that people may take can also cause bad breath. Your best dentist for treating bad breath in Dublin.


How can I avoid having bad breath?

Good oral hygiene is key. Dental check-ups and professional dental cleanings are essential every 6 months.


It is important to brush your teeth twice a day for 2-3 minutes using a fluoride toothpaste. Electric toothbrushes have been shown to be more effective than manual toothbrushes.


Flossing everyday is really important using string floss or inter-dental brushes. This removes trapped food from between your teeth.


Make sure to brush your tongue too. Bacteria love to build up on your tongue which can result in bad breath.


If you have persistent bad breath it is important to visit your dentist in Smile Hub Dental Clinic in Sutton for a comprehensive dental examination. One of our friendly and professional dentists will advise you on an oral health routine and perform a scale and polish for your teeth and gums if necessary.


Frequently Asked Questions

What are the causes of bad breath?

  • Morning bad breath due to the mouth drying up overnight. Bacteria quickly break down the bits of food left in the mouth resulting in an unpleasant stale smell
  • Strongly flavoured food such as garlic, onions and spices. Strong smelling drinks such as alcohol and coffee can cause bad breath
  • Medicines such as nitrates, chemotherapy drugs and tranquilisers
  • Smoking
  • Medical conditions such as diabetes, sinusitis, bronchitis and gastritis

How do you diagnose bad breath?

The best way to find out if you have bad breath is to ask a close friend or family member for their honest opinion. Booking an appointment with Smile Hub in Sutton is advisable so that your dentist can confirm if you have bad breath and what is the likely reason for this.

If your bad breath is caused by poor oral hygiene your dentist can advise you on how to keep your teeth and gums healthy. Regular dental examinations can help detect the early signs of tooth and gum disease which prevents bad breath developing. If your bad breath is food related you could keep a diary of the food you’re eating and any medications that you’re taking. In rare occasions following a visit to your dentist in Smile Hub you may be recommended to attend your GP to identify a medical cause of your bad breath. Please do not try to hide your bad breath before attending your dental check-up in Smile Hub as it may help your dentist to diagnose the problem.

How do I treat my bad breath?

  • Brush your teeth and gums regularly
  • Floss between your teeth
  • Keep your tongue clean

Keep your teeth and mouth healthy:

  • Choose a small-medium sized toothbrush with soft, multi-tufted synthetic bristles.
  • Replace your toothbrush every 2-3 months.
  • Brush your teeth for a minimum of two minutes each time.
  • Brush all areas of your teeth, and particularly where the teeth meet the gums.
  • Your dentist or hygienist may recommend a special single-tufted brush for specific problem areas of your mouth.
  • Use a separate toothbrush, or tongue scraper, to lightly brush your tongue (some toothbrushes have a ‘tongue cleaner’ on the reverse of the brush head).
  • Use dental floss to clean between your teeth and remove any trapped food that could cause tooth decay.
  • Your dentist may suggest daily rinsing with an anti-bacterial or anti-odour mouthwash (this should not replace brushing, but can be included in your daily routine).
  • Avoid brushing your teeth for 30 minutes after drinking an acidic drink, such as fruit juice, or eating acidic fruit, such as oranges, to help prevent tooth erosion.

How can my dentist help?

Your dentist can recommend the best way to clean your teeth and gums and show you any areas you might be missing. Regular 6 monthly check-ups with your dentist will make sure any plaque is removed from your teeth, especially in hard-to-reach areas. It will also ensure any signs of gum disease are treated early.

What if my dentures are causing bad breath?

Make sure to take dentures out at night to give your mouth a chance to rest and to clean your dentures twice daily.

Do not clean your dentures with toothpaste as this can scratch the surface of your dentures and cause stains to build up.
