Die breaks are issues that occur on the Die itself. If there is a small area that breaks off the die the metal from the blank planchet will flow into the void when struck. Then that would make it a Die Chip. It's never added metal to the coin. It's a worn die issue.
Welcome to CT. It appears the larger one in the hair is a die chip, which happens when dies are overused and parts break off. Better photos would help. For the best results, you should post "in focus," FULL IMAGE photos (after you upload your photo, two buttons appear: Thumbnail and Full Image, click Full Image and your photo appears full size on your post and are easily enlarged by clicking on it). Photograph coins on neutral backgrounds like black, grey, or white. Crop out superfluous background so just the coin shows (you can use https://www.remove.bg for free), and post photos with correct orientation so members don't have to turn their computer in some awkward fashion to view it properly. While it isn’t always necessary, it is nice to show both the obverse and reverse, even if your question is just about one side. Members can often give more valuable information having both sides to evaluate. Add close ups of areas you have questions about and make your questions as definitive as possible so we know what you are asking for. And try to have the best lighting possible to show the most favorable photo of the coin. Hope this helps in the future. Good luck.
Yes, those are die chips, which can be found frequently on modern Roosevelt dimes as @alurid mentioned. Cuds-on-Coins.com is a great resource for "broken-die" varieties. That site defines the limit between a die chip and a die break as 4mm (less than 4mm is a die chip; greater than or equal to 4mm is a die break). http://cuds-on-coins.com/interior-die-breaks-on-world-coins/
