Hi dewitrma, I'll take a try at answering your question. As you know, only the dreamer can fully interpret their dream within the context of their life.
sharp broken teeth could represent your anxieties about how you are both perceived; either by each other or by others. The sharp teeth could mean that you are not necessarily happy with the way you perceive your behaviour. It may be that you feel guilty of harsh words between you.
Consider what were the circumstances before the dream. If you both were on good terms, then it could mean that you are both concerned that your good relationship might be negatively affected.
Be aware of how you communicate with each other and others. An unkind word can leave a lasting impression and can do more damage to one's confidence than you may imagine.
Have a great day. It very great that you and your daughter are on the same wavelength.
All the best.
