Anyone know what this might mean?

(I do have teeth dreams every now and again, but not this brutal in nature to me, and also never having a good ending, just left with the rotten and lack of teeth usually.)

So I'm at my grandmas house for the entirety of the dream. Some family is here with me, both my sisters, my mom, and my grandma. I keep tonguing this little thing that I feel in the bottom tooth right before the wisdom tooth. It feels like it'll come out loose each time but its hard to budge. The whole time I'm thinking it's a piece of food or something. Then finally I feel it snap off and I feel 2 solid shards of something and instantly know what it is, it's pieces of mercury filling and I panic and spit it out into my hand so I don't accidentally swallow them. The main shard is larger than the little secondary bit. I run and show my family and I'm worried because I feel like mercury vapors are now going into my system. Then I start to eat for some reason, and then this girl who I don't know and don't know why she's in my grandmas house yells at me that I shouldn't be eating when I broke the mercury and that all the food touched it and went into my stomach. I panic and start to feel sick and contemplate making my self throw up the poisoned food in me, but I don't and instead try to shoot water in my mouth to clean it all out. Then my family leaves, they have to go somewhere for a little bit and I'm left there alone. For some reason I can't stop fixating on my teeth in the bathroom mirror, I look to see the tooth where the mercury broke off, and notice how disgusting and rotted all my teeth are. I become confused as to why nearly all my teeth now have mercury fillings because I thought I only had two. (In waking life I only have two and remembered this in my dream). There's brown spots and the teeth are yellow and sickly. I go and walk into the dining room area and stand there anxiously waiting for my family to come back, I feel like I need their help in the matter. Then while waiting I feel the upper tooth next to one of my big front tooth's become wiggly and I try to bight it back into place but then I hear this crackle noise that I knew meant the root just cracked out of the gum, then I just let it fall into my hand, I look at it and it's shaped weird I notice and it had two sharp thorn looking things that i guess were the roots, the tooth is brown and yellow and seems to be swollen. My mom comes home and I show her the tooth, she is disgusted by it rather than wanting to help me, she squeezes the tooth for some reason and I hear a crack and she drops it to the counter with disgust and says it's disgusting. I look at it and see she cracked the tooth open and it was completely filled with brown stuff that feel out of it that looks like beef jerky pr something. I just leave the tooth there and go look in the mirror again, because my mom left again. I look to see the spot where the tooth had fallen from, but I don't see any spot without a tooth, and then I realize that there must've been a tooth behind the tooth that just fell out, it relieves me. I examine it in the mirror, it's not aligned with my front teeth but I don't care, its smaller like maybe it'll grow in more, and its bright white and healthy. Then I feel a group of teeth on the bottom about a row of four of them feel really wiggle, and I try to bite them back into place, bite the roots back in, but they just wont, I hear that crackles noises of the roots forever displacing, so I let all four teeth fall into my hand. They're all yellow, I put them on the bathroom counter top and look in the mirror expecting a big spot on my gums with no teeth and also all the other teeth being disgusting, but then I'm shocked to see in the mirror all my teeth there, and they all look healthy, vibrant white, in alignment, I'm so shocked and pleased to see such thing I almost wanted to cry with joy, and I think to myself, my teeth have never looked so nice like this and that I shall want to smile to people, to everyone. The teeth felt strong, not on the verge of falling out like the other ones.

I will try to look for more precise interpretations later, but in general losing your teeth in dreams may mean that you're insecure about your appearance and/or interaction with others, and/or a feeling of helplessness. If this doesn't relates to you, then disregard the rest of this post. Seeing as how your teeth were rotten and were cracking up, the feelings may be or have been very strong. Your mother could be representing your subconscious self, or what your subconscious is trying to convey to you. It may be saying that your rotten teeth, or your feeling of insecure/hopelessness, is in fact not good for yourself and that's why you should abandon it. Mothers can always be represented as a warm presence, and your subconscious may have been trying to convey that to you to persuade you to let go of those feelings. That was apparent when the rotten tooth was replaced with a white one. Then, when all the other teeth started breaking, and they were all replaced with white, pretty ones, you gained a sense of happiness and wanting to show it to everyone.

If it does match up with your current situation, be proud of yourself. Be proud of how you look and how you feel around other people. That's the message your mind wanted to give you.

I really hope this helps. Happy dreams :D

Thank you fro your interpretation :)

Possibly your sister/mother has made you feel weird, judged etc. in the past. They don't understand your pain, your situation, possibly they blame you for something that they don't understand fully.
