Medela TheraShells Breast Shells

For nursing mothers dealing with sore, flat, or inverted nipples—or the discomfort of engorgement—Medela TheraShells offer gentle, practical relief that fits discreetly inside a bra. These breast shells are designed to protect tender nipples between feedings and to help draw out flat or inverted nipples, making latching easier for both mom and baby during the early weeks of breastfeeding.

The Medela TheraShells set (item 89930) includes two shells with two interchangeable back options. The sore nipple and engorgement backs feature ventilation openings that allow air to circulate around healing skin, while the flat and inverted nipple backs apply gentle, even pressure to encourage the nipple to protrude. This two-in-one design means you can address different needs with a single product rather than buying separate accessories.

Mothers often ask when to wear breast shells. The flat/inverted backs are typically worn between and before feedings to help shape the nipple, while the vented backs are worn to relieve pressure on cracked or sore skin and to protect the nipple from rubbing against clothing. Because engorgement can leak, the shells also help collect any drips, keeping bras drier. TheraShells are made without BPA and are constructed from smooth, lightweight material that's easy to clean and reassemble.

Proper fit matters—the shell should sit comfortably over the nipple without pinching the areola, and it works best under a supportive, slightly roomier nursing bra. If you're building out your feeding supplies, TheraShells pair naturally with pumping accessories, milk collection items, and other breastfeeding essentials from Medela and other trusted brands. Whether you're managing the first tender days of nursing or working through latch challenges, TheraShells offer a simple, mother-tested way to stay comfortable and keep breastfeeding on track.
