Tonsillitis is inflammation of the tonsils, two oval-shaped tissues at the back of your throat. These tissues are part of your immune system, helping to trap and filter bacteria and viruses that enter through your mouth and nose. When the tonsils become infected by these germs, they swell and become painful, causing the symptoms of tonsillitis. In Singapore’s tropical climate, with high humidity and frequent temperature changes between air-conditioned spaces and outdoor environments, respiratory infections including tonsillitis can occur. The condition affects both children and adults, though it may be more common in school-aged children due to close contact in classrooms.

What is Tonsillitis?
Types of Tonsillitis
- Acute Tonsillitis: Acute tonsillitis develops suddenly and may last several days to weeks. This represents a single episode of infection that can respond to appropriate treatment. Cases may be viral or bacterial in nature, with bacterial infections including Group A Streptococcus among the possible causes.
- Recurrent Tonsillitis: Recurrent tonsillitis involves multiple episodes of acute tonsillitis within a year. Medical criteria may define this as multiple episodes annually or over consecutive years. Patients may experience disruption to daily activities due to recurring illness.
- Chronic Tonsillitis: Chronic tonsillitis presents as a persistent infection lasting months. Patients may experience ongoing symptoms such as chronic sore throat, bad breath, and tender lymph nodes. The tonsils may appear enlarged with visible debris in the crypts. This form can develop after repeated acute infections have affected the tonsil tissue.
Causes & Risk Factors
Causes
Tonsillitis occurs when infectious agents overwhelm the tonsils’ defensive capabilities. Viral infections are a common cause, with typical causes including adenovirus, rhinovirus, influenza virus, and Epstein-Barr virus. Bacterial infections are less common but tend to cause more severe symptoms. Group A Streptococcus (Strep throat) is a significant bacterial cause, though other bacteria such as Staphylococcus aureus and Pneumococcus can also trigger infections.
Risk Factors
- Age: Children may face higher risk due to developing immune systems and close school contact.
- Exposure to germs: Frequent contact with large groups may increase infection risk.
- Weakened immunity: Stress, poor nutrition, or underlying health conditions may compromise natural defences.
- Environmental irritants: Air pollution can irritate throat tissues.
- Poor oral hygiene: May allow bacterial overgrowth in the mouth and throat.
- Seasonal changes: Transitions between seasons may trigger respiratory infections.
- Previous tonsillitis episodes: Past infections may leave tonsils more susceptible to future infections.
- Smoking or secondhand smoke exposure: May irritate throat tissues and impair immune function.
Signs & Symptoms
Mild Symptoms
- Throat discomfort or scratchiness
- Mild difficulty swallowing
- Low-grade fever
- Slightly swollen tonsils with minimal redness
- Mild fatigue or general malaise
- Reduced appetite
- Slight voice changes
Moderate Symptoms
- Significant throat pain radiating to the ears
- Painful swallowing affecting food and liquid intake
- Moderate fever
- Visibly red, swollen tonsils with white or yellow patches
- Swollen, tender neck lymph nodes
- Headache and body aches
- Bad breath (halitosis)
- Noticeable voice changes or muffled speech
Severe Symptoms
- Severe throat pain preventing swallowing of saliva
- High fever
- Difficulty breathing or noisy breathing
- Drooling due to inability to swallow
- Severely enlarged tonsils meeting in the middle

Symptoms may develop after exposure to infection. Viral tonsillitis often begins gradually with cold-like symptoms, whilst bacterial tonsillitis tends to start abruptly with severe throat pain and high fever.
Experiencing these symptoms?
Consult with an ENT specialist for an accurate diagnosis and treatment plan.
When to See an ENT Specialist
Seek medical attention for tonsillitis to ensure proper treatment and prevent complications. Consult an ENT specialist immediately if you experience difficulty breathing or swallowing, drooling, fever, or throat pain preventing fluid intake. Also seek medical care for symptoms suggesting peritonsillar abscess, such as severe one-sided throat pain, difficulty opening the mouth, or a “hot potato” voice.
Schedule a consultation if you experience recurring episodes of tonsillitis, persistent sore throat, or chronic bad breath with throat discomfort. During a consultation, an ENT specialist can perform a throat examination using medical instruments, review your medical history and symptom patterns, and may order diagnostic tests to determine the infection type.
Diagnosis & Testing Methods
Accurate diagnosis of tonsillitis involves clinical examination combined with appropriate diagnostic tests. An ENT specialist begins with a detailed medical history, focusing on symptom duration, frequency of episodes, and previous treatments. The physical examination includes direct visualisation of the tonsils using a lighted instrument, palpation of neck lymph nodes, and assessment of ear and nasal passages for related infections.
A rapid streptococcal antigen test can provide results to help identify streptococcal infections that may require antibiotic treatment. For analysis, a throat culture may be performed. The culture can identify specific bacteria and determine antibiotic sensitivity patterns.
Blood tests, including complete blood count and inflammatory markers, may help assess infection severity and rule out complications. In cases of suspected abscess or chronic tonsillitis, imaging studies such as ultrasound or CT scan may be recommended to evaluate deep tissue involvement.
Treatment Options Overview
Medical Management
- Antibiotic Therapy: For bacterial tonsillitis, particularly streptococcal infections, antibiotics may be prescribed as the primary treatment. Penicillin or amoxicillin typically serves as first-line therapy, taken for 10 days to help achieve bacterial eradication. Patients allergic to penicillin may receive alternative antibiotics such as azithromycin or cephalosporins. Completing the full antibiotic course aims to prevent complications and reduce antibiotic resistance development.
- Pain and Fever Management: Symptoms can be managed with paracetamol and ibuprofen, which may help reduce fever and throat pain when taken at regular intervals. These medications may work when alternated every 3-4 hours during acute symptoms. Your ENT specialist can provide specific dosing guidelines based on your age and medical history.
- Throat Sprays and Lozenges: Topical treatments may provide targeted relief directly to inflamed tissues. Antiseptic throat sprays containing chlorhexidine or benzydamine may help reduce bacterial load and provide numbing effects. Medicated lozenges with local anaesthetics may offer temporary pain relief while stimulating saliva production to keep the throat moist.
In-Office Procedures
- Tonsil Cryptolysis: For chronic tonsillitis with debris accumulation, cryptolysis may help reduce the depth of tonsil crypts where bacteria hide. This minimally invasive procedure uses laser or radiofrequency energy to smooth the tonsil surface, which may help reduce infection recurrence. The procedure typically takes approximately 30 minutes under local anaesthesia with minimal downtime.
- Abscess Drainage: Peritonsillar abscesses may require prompt drainage to help prevent spread of infection. An ENT specialist may perform needle aspiration or incision and drainage under local anaesthesia, which may provide relief from severe pain and swelling. Patients may experience improvement within the following days.
Surgical Options
- Tonsillectomy: Complete surgical removal of the tonsils may be considered as a treatment option for recurrent or chronic tonsillitis. Modern techniques include traditional dissection, coblation (using radiofrequency energy), or laser tonsillectomy. The procedure typically takes approximately 45 minutes under general anaesthesia. Recovery may require up to 14 days, during which dietary modifications and pain management are part of the treatment plan.
- Partial Tonsillectomy (Tonsillotomy): This technique preserves some tonsil tissue while removing the problematic portions. Particularly suitable for children, partial tonsillectomy may help reduce postoperative pain and bleeding risk compared to complete removal. The procedure aims to address obstructive symptoms while maintaining some immune function.
Supportive Care Measures
- Hydration Therapy: Maintaining adequate fluid intake may help prevent dehydration and thin mucus secretions. Warm liquids like herbal teas may soothe throat tissues, while cold drinks and ice chips may provide numbing relief. A specialist may recommend IV hydration for severe cases with swallowing difficulty.
- Dietary Modifications: During acute infection, soft, non-irritating foods may help prevent additional throat trauma. Smooth soups, yoghurt, and mashed foods can provide necessary nutrition without causing pain. Avoiding acidic, spicy, or rough-textured foods may support healing and improve comfort.
Every patient’s condition is unique.
Our ENT Specialist can assess your specific situation and recommend the most suitable treatment approach for you.
Complications if Left Untreated
Untreated tonsillitis may progress to complications affecting multiple body systems. Peritonsillar abscess, a collection of pus behind the tonsil, can develop in bacterial infections and may obstruct the airway if not promptly drained. The infection may spread to deep neck spaces, potentially causing complications including mediastinitis or sepsis.
Chronic tonsillitis can lead to persistent symptoms that may impact quality of life. Ongoing inflammation may cause sleep disruption from snoring or sleep apnoea, particularly when enlarged tonsils obstruct the airway. Children may experience poor school performance due to frequent absences and chronic fatigue. In some cases, untreated streptococcal tonsillitis may trigger post-infectious complications such as rheumatic fever affecting the heart valves, or glomerulonephritis causing kidney inflammation. These conditions emphasise the importance of appropriate medical evaluation and treatment for throat infections. Individual outcomes may vary. This information is provided for educational purposes and should not replace professional medical advice.
Prevention
While complete prevention of tonsillitis isn’t always possible, several measures may help reduce infection risk. Frequent handwashing with soap and water is an effective prevention method, particularly after using public transport or before eating. Using alcohol-based hand sanitisers when soap isn’t available can provide additional protection.
Maintaining good oral hygiene through regular brushing, flossing, and using antiseptic mouthwash may help reduce bacterial load in the mouth. Replace toothbrushes every three months or after illness to help prevent reinfection. During Singapore’s haze periods, wearing masks and limiting outdoor activities may help protect throat tissues from irritation.
Staying well-hydrated helps keep mucous membranes moist and better able to trap pathogens. Adequate sleep, balanced nutrition rich in vitamins C and D, and regular exercise may help strengthen immune function. Avoiding close contact with infected individuals and not sharing eating utensils or drinks can help prevent direct transmission of infectious agents.

Frequently Asked Questions (FAQ)
How long is tonsillitis contagious?
The contagious period depends on the cause. Viral tonsillitis may remain contagious for several days from symptom onset. Bacterial tonsillitis, particularly streptococcal infections, may remain contagious until after starting antibiotics. Without antibiotic treatment, bacterial tonsillitis can remain contagious for an extended period. During the contagious period, avoid close contact with others, practise good hygiene, and stay home from work or school to prevent spreading the infection.
Can tonsillitis resolve without antibiotics?
Viral tonsillitis, which accounts for many cases, may resolve without antibiotics through supportive care alone. The immune system can fight off viral infections with adequate rest, hydration, and symptom management. However, bacterial tonsillitis, particularly streptococcal infections, requires antibiotic treatment to prevent complications and support recovery. An ENT specialist uses diagnostic tests to determine whether antibiotics are necessary, ensuring appropriate treatment whilst avoiding unnecessary medication.
What’s the difference between tonsillitis and strep throat?
Strep throat is a specific type of bacterial tonsillitis caused by Group A Streptococcus bacteria. Strep throat cases involve tonsil inflammation, though not all tonsillitis is strep throat. Strep throat may cause symptoms including fever, throat pain, and white patches on the tonsils. It requires antibiotic treatment and can lead to complications if untreated. A specialist uses rapid strep tests to make this important distinction.
When should I consider tonsillectomy for recurring tonsillitis?
Medical guidelines suggest considering tonsillectomy for frequent episodes of tonsillitis over consecutive years. Tonsillectomy may also be recommended for chronic tonsillitis unresponsive to medical treatment, recurrent peritonsillar abscesses, or tonsils causing breathing or swallowing difficulties. An ENT specialist can evaluate your specific situation, considering infection frequency, severity, and impact on daily life.
Can adults get their tonsils removed?
Yes, adults can undergo tonsillectomy, though recovery may take longer than in children. Adult tonsillectomy is performed for the same indications as paediatric surgery: recurrent infections, chronic tonsillitis, or obstructive symptoms. The procedure technique remains similar, but adults may experience more postoperative pain and require time for recovery. Many adults report quality of life improvement after resolving chronic tonsil problems.
How can I manage tonsillitis pain at home?
Home management focuses on symptom relief whilst your body fights the infection. Gargle with warm salt water to help reduce swelling and clear debris. Use throat lozenges or sprays for temporary relief. Stay well-hydrated with warm teas, cool drinks, or ice chips based on preference. Rest your voice and get adequate sleep to support immune function. However, home remedies complement but don’t replace professional medical treatment when needed.
