Tonsil removal is typically recommended when you’re getting frequent throat infections, at least seven in a single year, five per year for two consecutive years, or three per year for three consecutive years. These thresholds, known as the Paradise criteria, are the standard most doctors use to decide whether surgery makes sense. But recurring infections aren’t the only reason tonsils come out. Sleep-disordered breathing, abscesses, persistent tonsil stones, and even suspected cancer can all tip the scale toward surgery.
The Infection Frequency Thresholds
The clearest path to tonsillectomy is a pattern of frequent, documented throat infections. The American Academy of Otolaryngology’s clinical guidelines lay out specific numbers:
- Seven or more episodes in a single year
- Five or more episodes per year for two years in a row
- Three or more episodes per year for three years in a row
Each episode needs to be backed up with at least one clinical sign: a fever above 101°F, swollen lymph nodes in the neck, white or yellow patches on the tonsils, or a positive strep test (either a rapid swab or a throat culture). This documentation matters. If you’ve been treating sore throats at home without seeing a doctor, those episodes may not count toward the threshold because there’s no medical record confirming the severity.
If you don’t quite meet those numbers, your doctor may still consider surgery based on what the guidelines call “modifying factors.” These include allergies or intolerances to multiple antibiotics (making infections harder to treat), a history of more than one peritonsillar abscess, or a rare condition called PFAPA syndrome that causes recurring fevers and mouth sores in children. Below those thresholds, the official recommendation is watchful waiting, meaning your doctor monitors the pattern over time rather than jumping to surgery.
When Breathing Problems Point to Surgery
Enlarged tonsils can physically block your airway, especially during sleep. In children, this is one of the most common reasons for tonsillectomy, sometimes even more common than infections. Signs that your tonsils (or your child’s) are causing airway obstruction include loud snoring, pauses in breathing during sleep, restless sleep, mouth breathing, and daytime sleepiness or irritability that doesn’t match how many hours of sleep were logged.
Obstructive sleep apnea is diagnosed through a sleep study, which measures how many times per hour breathing stops or becomes dangerously shallow. In children, more than one interruption per hour combined with symptoms is enough to flag a problem. Adults with enlarged tonsils contributing to sleep apnea may also be candidates, particularly if a CPAP machine hasn’t worked well or if the tonsils are clearly the source of the obstruction. Your doctor will examine the size of your tonsils relative to your airway and may use a small camera to check whether tissue at the base of the tongue is also involved.
Abscesses, Tonsil Stones, and Other Red Flags
A peritonsillar abscess is a pocket of pus that forms next to the tonsil, usually after a bad throat infection. It causes intense one-sided throat pain, difficulty swallowing, fever, and sometimes a muffled voice. A single abscess in someone with no history of tonsillitis doesn’t automatically mean the tonsils need to come out. But if you’ve had more than one abscess, or if you already had a pattern of recurrent tonsillitis before the abscess developed, tonsillectomy is generally recommended to prevent further episodes.
Tonsil stones are another reason adults seek removal. These small, calcified deposits form in the crevices of the tonsils and can cause persistent bad breath, a feeling of something stuck in the throat, and mild soreness. Tonsil stones alone don’t always lead to surgery, but when they’re large, frequent, and significantly affecting your quality of life despite regular cleaning efforts, removal becomes a reasonable option.
Asymmetry is worth paying attention to. If one tonsil is noticeably larger than the other, or if a tonsil has changed in size or appearance, your doctor may recommend removal to rule out a tumor. This is relatively uncommon, but an unexplained one-sided enlargement, especially in an adult, warrants a biopsy.
What Adults Should Know Versus Children
Most of the formal clinical guidelines focus on children ages 1 to 18, but adults undergo tonsillectomy for many of the same reasons: recurrent infections, sleep apnea, abscesses, tonsil stones, chronic sore throat, and suspected malignancy. The infection frequency thresholds are generally applied the same way for adults, though doctors may weigh the impact on your work and daily life more heavily when making the call.
One important difference is recovery. Adults consistently have a harder time bouncing back than children do. The pain tends to be more intense, the risk of complications is slightly higher, and healing takes longer. This doesn’t mean adults shouldn’t get the surgery when it’s warranted, but it does mean the decision involves weighing a tougher recovery against the long-term benefit of fewer infections or better breathing.
What Recovery Actually Looks Like
Full recovery takes about two weeks. Plan to take at least 10 days off work or school. The first week is the hardest: your throat will be sore, swallowing will hurt, and you’ll want to stick to soft, cool foods like yogurt, applesauce, smoothies, and popsicles. Crunchy or spicy foods can irritate the surgical site and should be avoided until you’re comfortable eating normally again. Most people find that pain improves steadily after the first week, though it can spike briefly around days 5 to 7 as the scabs in the throat begin to dissolve.
The most serious complication to watch for is bleeding, which happens in roughly 2% to 5% of cases. It can occur anytime within the first 14 days after surgery, and severity ranges from blood-tinged saliva to significant hemorrhage that requires emergency attention. Small amounts of pink or blood-streaked spit are common and usually not dangerous, but spitting up bright red blood or swallowing enough blood to vomit means you need immediate medical care.
How to Track Your Symptoms Before an Appointment
If you suspect you might need your tonsils removed, the most useful thing you can do right now is start keeping a log. Write down every sore throat episode with the date, your symptoms, whether you had a fever (and how high), and whether you saw a doctor. If you get a strep test, record the result. This kind of documentation is exactly what your doctor needs to evaluate whether you meet the criteria for surgery. Without it, even a clearly problematic pattern can be hard to prove from memory alone.
Bring this log to your appointment with an ear, nose, and throat specialist. They’ll examine your tonsils, review your infection history, assess your airway, and help you decide whether the benefits of surgery outweigh the recovery. For many people who meet the thresholds, tonsillectomy leads to a significant drop in throat infections and a noticeable improvement in quality of life.
