Introduction

One of the most common diseases, tonsillitis, also known as inflammation of the tonsils, accounts for approximately 1.3% of all outpatient visits.¹ Let us begin with a brief overview of tonsils before moving on to our main topic of discussion.

Tonsils are lumps of tissue (classified as lymphoid tissue). They can be found in the back of the throat on both the left and right sides. Tonsils play an important role in immunity and the body's defense against infections and pathogens. They serve as the first line of defense against inhaled or ingested pathogens, forming the initial immunological response.

What is tonsillitis?

Tonsillitis is an infection of the tonsils located on the sides of the throat. It starts suddenly and is painful but it usually goes away within one or two weeks. It may also return multiple times and stay for an extended period of time. It is both painful and unpleasant in nature. The associated complications are uncommon. It is usually caused by an infection with bacteria or a virus. Tonsillitis can have a lot of the same symptoms as a bad cold or flu.

What are these symptoms?

The most common symptoms of tonsillitis include:

• Sore throat
• Swollen and red tonsils with a yellowish coating
• Difficulty in swallowing
• Swollen and painful lymph nodes in the neck
• Fever
• Headache
• Fatigue and tiredness
• Loss of appetite
• Bad breath
• In children, atypical symptoms such as stomach ache, nausea, or vomiting

What factors contribute to tonsillitis?

Infections caused by bacteria or viruses can lead to the development of tonsillitis. When an infected person speaks or sneezes, germ-containing droplets are released into the air. A healthy person who comes into contact with these droplets becomes infected.

Up to 70% of all cases of acute tonsillitis are caused by viruses.² The most common viral causes are those that cause the common cold, such as adenovirus, influenza virus, or mycoplasma.

Tonsillitis can develop in children and young adults infected with Epstein-Barr virus (EBV), which causes infectious mononucleosis (also known as "mono" or glandular fever). Herpes simplex virus, cytomegalovirus, and measles virus have all been linked to tonsillitis.

Bacteria are responsible for 15-30% of tonsillitis cases.³ Group A beta-hemolytic streptococcus (GABHS) is the most common type of bacteria that cause tonsillitis. Bacterial tonsillitis is also known as strep throat.

Tonsillitis can occasionally result from scarlet fever, which is also caused by bacteria. 

What are the risk factors for tonsillitis?

Studies have found a strong association between tonsillitis and the following factors:

• A young age
• Unhygienic living conditions
• Balanced diet
• Stressful environment
• Use of sour or spicy foods
• Poor oral hygiene

According to studies, males were more likely to contract the disease than females.⁴ Tonsils in children aged up to 6 years are larger than in adults, making them an easy target for tonsillitis.

How important is maintaining good oral hygiene?

Maintaining good oral hygiene is an important part of staying healthy. The mouth is a way for microorganisms to get into the body. The digestive system begins with the mouth. As a result, any disease-causing organism in the mouth can spread to the rest of the body. Studies have shown that taking care of your teeth and gums can make you less likely to get tonsillitis. A survey report said that people with bad breath and poor oral hygiene (teeth that were decayed or filled) were more likely to get acute tonsillitis. Oral biofilm (dental plaque) forms on tooth surfaces and serves as a common reservoir for pathogens that cause tonsillar infections. As a result, poor oral hygiene can exacerbate a bacterial infection that leads to acute tonsillitis.

How bad oral hygiene can lead to tonsillitis?

It has been shown that not taking care of your teeth and gums properly can make you more likely to get diseases inside and outside of your mouth and throat, like tonsillitis.

A wide range of microorganisms colonize tonsils and all other epithelium-lined interface surfaces of the body. Due to constant surface renewal by shedding, macrobiotics live in harmony with the host.

While in the mouth, however, teeth provide hard, non-shedding surfaces where bacteria can build up in large amounts. Accumulation of plaque or its hardened form, calculus, around the teeth is a sign of bad oral hygiene and is the main cause of oral cavities, gingivitis, and periodontitis. 

These oral lesions serve as reservoirs for bacterial antigens, gram-negative bacteria, cytokines, and other proinflammatory mediators that can cause infections in other parts of the body, such as tonsils.

What are the preventive measures that are being taken?

The risk of developing tonsillitis can be significantly reduced by practicing proper oral hygiene and taking the necessary precautions. Some of these precautionary measures are:

Improved oral care

• Spend two minutes brushing your teeth every day, at least twice, and brush your tongue too
• Stick to fluoride-containing toothpaste and soft-bristled toothbrushes
• Use floss, a water flosser, or other specially designed products to clean between your teeth every day
• Use antibacterial mouthwash
• Every three to four months, you should get a new toothbrush. If the bristles have worn or flared out, do it sooner

Routine dental check-ups

• Visit your dentist at least once a year for a checkup and cleaning. Depending on your needs, your dentist may recommend more frequent visits or cleanings
• Contact your dentist as soon as you notice any oral health issues. Maintaining good oral health improves your overall health

Healthy lifestyle choices

• Stay hydrated by drinking plenty of water
• Eat a healthy and balanced diet rich in nutrients
• Avoid smoking and use of tobacco

FAQs

What is tonsil?

Tonsils act as filters, trapping germs that would otherwise enter your airways and cause infection. They also make antibodies to fight infection. However, bacteria or viruses can sometimes make them weak. This can make them swollen and inflamed. Tonsillitis is common, especially in children.

What to eat with tonsillitis?

Soft Foods: Choose foods that are soft and easy to swallow, like smoothies, mashed potatoes, yogurt, and soups. These foods are easy on the throat and give you the nutrients you need without making it worse.

How to cure tonsils fast?

Saltwater gargles can provide immediate relief from tonsillitis.

What is the reason for tonsillitis?

Tonsillitis is usually caused by viruses but it can also be caused by bacteria.

How is tonsillitis spread?

The infection is usually spread through droplets from coughing or sneezing or through touching contaminated surfaces. How long you're contagious depends on the cause of your tonsillitis. You're usually contagious a couple of days before you develop symptoms and you might be contagious up until your symptoms go away.

What fruit is good for a sore throat?

• Bananas are soft fruits that are good for you, soothe the throat, and fill you up.
• Studies show that pomegranate juice may help reduce swelling and fight off infections.

Is honey good for tonsils?

With its anti-inflammatory properties, it can help ease the pain and coughing. A quick fix for sore tonsils at home is to mix a tablespoon of ginger juice with a tablespoon of honey and warm water.

How to prevent tonsillitis?

• Keep your distance from people who have tonsillitis or a sore throat
• If someone has tonsillitis or a sore throat, do not share your cutlery, drinking glasses, toothbrushes, or other personal items
• Always wash your hands
• You should put your hand over your mouth when you cough or sneeze

Summary

If you do not take care of your teeth and gums, you may be more likely to get tonsillitis. This is because bacteria can cause infections in the mouth and throat. Neglecting oral hygiene can cause harmful bacteria to build up on the teeth, gums, and tongue, which can cause infections that can spread to the tonsils. This can make the tonsils swell and get infected, which can lead to symptoms like fever, sore throat, and trouble swallowing. Regular brushing, flossing, and dental check-ups are all good ways to keep harmful bacteria in check in your mouth and lower the risk of tonsillitis.
