Children with language skills rarely need surgery to help them eat.
It was found that two-thirds of children sent to the procedure did not need it and could be fed with other support.
A tongue-tie occurs when a strip of skin that has a tongue and a floor of the mouth is shorter than usual. It can affect the feeding, although not always.
British experts said that the procedure can be avoided with "right support".
"No real data"
Between 4% and 11% of infants are born with tongue or ankylogenesis.
This may mean that infants can not open their mouths widely enough to breastfeed.
You can offer a simple procedure called frenellectomy, where the language is cut off.
In very young children, it can be performed even under local anesthesia.
The US study shows that the number of frenellectomies is increasing, from 1200 in 1997 to 12,400 in 2012.
NHS Digital numbers show at least 4320 were held in England in 2015-16 – and this figure is likely to be underestimated, because such a fast procedure can not always be recorded.
In a US study published in the JAMA ophthalmologist – head and neck surgery, 115 babies were treated, which averaged about a month.
All of them were sent to a surgical procedure – but 63% were able to successfully breastfeed with the help of specialists, including language and language therapists.
Dr. Christopher Hartnick, of the Massachusetts Eye and Eye Hospital, who led the research, said: "We have seen that the number of operations for removing language and upper lip increases without any real data that would have shown that they are effective for breastfeeding "
NCT Adviser for Breastfeeding Jane Moffett said: "Many women experience problems feeding their children in the first days and weeks.
"In some cases, it can be tied to the language.
"There is limited evidence that the children need a language unit, but not what.
"Services also vary significantly across the UK, with some areas having no provision for the NHS and worries about excessive diagnosis in other countries.
If you think your child has a tie or worries that he or she is not breastfeeding properly, consult a breastfeeding counselor, midwife or a medical visitor.
"Getting support early can change everything."
Prof. Mary Fetrell from the Royal College of Pediatrics and Child Health said: "For some people, the language may be the cause of poor breastfeeding and pain in the mother's nipple, and the procedure may correct the movement restrictions and allow for more effective breastfeeding for the baby, and comfort for mom.
"However, parents need good support and breastfeeding tips before considering surgery because, as the study shows, it can sometimes be avoided with proper support.
"Although this new study sheds light on this issue, so far we do not have enough data from qualitative research to find out what is best for breastfeeding."
