Tonsil removal, or tonsillectomy, is typically recommended when you’re getting seven or more throat infections 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 most widely used benchmark in both the U.S. and the U.K. But recurrent infections aren’t the only reason. Sleep-disordered breathing, suspected cancer, recurring abscesses, and even chronic bad breath from tonsil stones can all be valid reasons for surgery.
The Infection Frequency Threshold
The clearest, most evidence-backed indication for tonsillectomy is recurrent throat infections that hit specific numbers. The Paradise criteria set the bar at:
- Seven or more documented sore throats in one year
- Five or more per year for two consecutive years
- Three or more per year for three consecutive years
These criteria were developed for children ages 3 to 15, and research shows that children who meet them experience modest, short-term reductions in sore throats after surgery. Children who don’t meet these thresholds generally don’t benefit enough to justify the procedure. The key word here is “documented.” Your doctor typically wants infections confirmed by a clinic visit, a positive strep test, or a record of antibiotic treatment, not just your recollection of being sick.
How the Rules Differ for Adults
There are no separate, well-validated surgical guidelines written specifically for adults. In practice, most ear, nose, and throat specialists apply the same Paradise criteria to adult patients, and this is considered a reasonable approach even though the research base is thinner. Two studies have reported short-term benefit from tonsillectomy for recurrent throat infections in adults, but large-scale trials are limited.
That said, the long-term data for adults is encouraging. A study tracking adults after tonsillectomy found that doctor visits for sore throats dropped from an average of five per year before surgery to less than one per year afterward, and that improvement held at both 14 months and seven years post-surgery. Antibiotic use fell from about four courses per year to two and a half. Around 70% of patients reported no throat-related doctor visits at all in the years following surgery. Work absences also declined significantly.
Sleep-Disordered Breathing
Enlarged tonsils that physically block the airway during sleep are one of the most common reasons for tonsillectomy in children. When tonsils are large enough to cause snoring, mouth breathing, restless sleep, or pauses in breathing (obstructive sleep apnea), surgery is often the first-line treatment. In adults, sleep apnea is more commonly managed with other approaches, but tonsillectomy may still be considered when oversized tonsils are clearly contributing to the obstruction.
Peritonsillar Abscess
A peritonsillar abscess, sometimes called quinsy, is a pocket of pus that forms beside the tonsil. It has historically been considered a strong indication for tonsillectomy, sometimes performed during the acute episode and sometimes scheduled weeks later. The decision often depends on your age and how many throat infections you’ve had before the abscess. A single abscess in someone with no history of recurrent infections may be treated with drainage and antibiotics alone, while recurring abscesses or abscesses on top of a long history of tonsillitis make a stronger case for removing the tonsils entirely.
Tonsil Stones and Chronic Bad Breath
Tonsil crypts, the small pockets on the surface of your tonsils, can trap food debris, bacteria, and dead cells that harden into tonsil stones. These stones cause persistent bad breath that doesn’t respond to normal oral hygiene. While tonsil stones alone aren’t as firmly established as an indication for surgery compared to recurrent infections, case series have reported that tonsillectomy or crypt ablation resolves halitosis in 75% to 98% of cases. The Mayo Clinic lists severe halitosis linked to tonsil stones as a recognized reason for the procedure.
Chronic tonsillitis, where the tonsils stay persistently inflamed and uncomfortable even between acute infections, is another reason some people pursue surgery. It’s considered a “less validated” indication, meaning the research supporting it isn’t as robust, but it’s still a common and accepted reason for referral to a specialist.
Ruling Out Cancer
When one tonsil is noticeably larger than the other, your doctor may recommend removal to examine the tissue under a microscope. Asymmetric tonsils can be completely harmless, and many people are referred after the enlargement is noticed incidentally. But tonsil cancer, including squamous cell carcinoma and lymphoma, needs to be excluded. Red flag symptoms that raise concern include unexplained weight loss, difficulty swallowing, pain when swallowing, and persistent hoarseness. In these situations, tonsillectomy serves a diagnostic purpose as much as a therapeutic one.
PFAPA Syndrome in Children
PFAPA syndrome causes recurring fevers, mouth sores, sore throat, and swollen lymph nodes in young children on a predictable cycle, often every few weeks. It’s not caused by infection, so antibiotics don’t help. Tonsillectomy is remarkably effective for this condition. In one long-term follow-up study, 91% of children had complete resolution of symptoms immediately after surgery. Of the remaining patients, one had a single fever episode after the procedure and then no further attacks, and another had a few episodes before achieving full remission within three months.
What Recovery Looks Like
Full recovery from tonsillectomy takes about two weeks. Most doctors recommend taking at least 10 days off work or school. Pain and discomfort are normal during this period and generally improve steadily over the first week or two. Adults tend to have a harder recovery than children, with more pain and a longer time before they feel fully normal.
The primary surgical risk is bleeding. A meta-analysis covering studies from 2005 to 2024 found that bleeding during or shortly after the operation occurs in about 1% of cases. Delayed bleeding, which typically happens five to ten days after surgery as the scabs in the throat begin to dissolve, is more common at roughly 5.8%. Most delayed bleeding episodes are minor, but some require a return to the hospital.
When the Case for Surgery Is Strongest
The decision to remove tonsils is strongest when you clearly meet the Paradise criteria with documented infections, when enlarged tonsils are disrupting sleep and breathing, when an abscess keeps coming back, or when asymmetry raises concern about malignancy. It’s a reasonable conversation to have with a specialist when you’re dealing with chronic tonsillitis, persistent tonsil stones causing social distress from bad breath, or PFAPA syndrome that isn’t resolving on its own. In all of these scenarios, the benefits of surgery need to be weighed against two weeks of recovery and a small but real bleeding risk.
