Bad Taste and Smell in Your Mouth? The Dental Hygiene Facts You Need to Know

If you wake up in the morning with a bad taste or smell in your mouth, you’re not alone. Morning breath is an extremely common issue and affects most people at some point in their lives. It is typically caused by not brushing your teeth properly before you go to bed at night, and usually fades after following your dental hygiene routine upon waking. If, however, you find the problem persisting even after your morning clean, you may have a problem that needs further investigation.

Getting to The Bottom of Bad Breath

Bad breath, also known as halitosis, despite being a taboo subject in more social circles, is one of the concerns most frequently presented to the dentist. A bad taste in your mouth, also known as dysgeusia, is also fairly common. The good news is that both these issues can usually be solved easily once addressed.

Ignoring the issue, however, means the problem may worsen and become more complicated to treat. Dental hygiene facts dictate that early treatment is key, and making an appointment with your dentist as soon as symptoms appear is an important first step. If you notice that you regularly wake up with a bad taste or smell in the mouth, your mouth feels different to normal, and either of these symptoms are persisting post-clean, it’s time to make an appointment.

Good Dental Hygiene: Facts to Inform Your Routine

It is essential that you look after your teeth properly from an early age to prevent dental health concerns as you get older. Humans have only one set of natural adult teeth and, despite advances in dental technology, it is important to remember that no alternatives are as ideal as your original teeth. Good dental hygiene is therefore crucial to maintaining healthy teeth over time.

This includes:

•  Brushing your teeth with a suitable toothbrush and toothpaste every morning and before bed at night
•  Flossing between your teeth and after meal times
•  Using a suitable mouthwash to remove lingering food particles and bacteria
•  Most importantly, visiting your dentist on a regular basis

According to best-practice dental hygiene facts, individuals benefit most when visiting their dentist at least once every six months. If you are prone to dental health concerns such as bad breath or cavities, it may benefit you to schedule visits more often.

Your dentist is able to clean your teeth in ways that are not possible at home, plus identify any concerns earlier on and treat them appropriately before they escalate.

What Happens When You Don’t Look After Your Teeth Properly?

When you do not clean your teeth properly, bacteria and food particles linger. These food particles rot, causing a bad smell or taste in the mouth. When you eat or drink, bacteria in your mouth multiply, producing sulphur compounds that contribute to these unpleasant odours. Properly brushing and flossing your teeth regularly is usually enough to remove food particles and lingering bacteria, leaving your mouth clean and fresh.

Poor Dental Hygiene: Facts About Common Diseases

However, in the absence of a good dental hygiene routine, you may find that bad breath or a bad taste in your mouth either won’t go away or comes back very quickly despite brushing. In this instance, it is important to visit your dentist as soon as possible.

These symptoms could lead to gum disease or more serious periodontal disease. One of the main tell-tale signs of these conditions is bad breath, often accompanied by a metallic taste in your mouth. Gum and periodontal disease are caused by poor dental hygiene but also other factors, including underlying illnesses such as diabetes, or poor lifestyle choices such as smoking.

Understanding Dental Disease

Your dentist will be able to identify the issue and then provide you with a solution. If you are suffering from underlying health issues, for example, diabetes, certain respiratory disorders, or a liver or kidney disorder, this can sometimes have a direct effect on your oral health. Certain medications can also have an ill effect on your teeth, such as antacids, antibiotics and chemotherapy. In these cases, it is important to visit the dentist more regularly and maintain better dental hygiene to reduce health risks.

Dental Hygiene Facts to Inform Treatment

If your concerns are caused as a result of smoking, excessive drinking or other poor lifestyle choices, you may want to reconsider certain behaviours in an effort to improve the state of your teeth, as well as your overall health and well-being.

If you have developed bad breath and a bad taste in your mouth because of poor dental hygiene, this is usually a straightforward issue to address. Your dentist will advise how you can look after your teeth better and may recommend you to a hygienist. They can help you clean your teeth further, remove the bacteria underneath your gums responsible for gum and periodontal disease and help you on your way to enjoying better dental health.

Ignoring your symptoms or avoiding the dentist can cause simple issues like bad breath or a bad taste in the mouth to progress quickly to gum and periodontal disease, or further complications. If you suspect you have issues that need to be addressed, make an appointment with your dentist to learn more about important dental hygiene facts and how to treat or prevent issues with the teeth and gums.
