short term solution...try oil-pulling. I'm betting that this will pass. Many of us have noted a transient increase in all sorts of things from breast pain to sore throat to discharge from eyes...anyway, here's an iteresting read on Iodine & the salivary glands:

Iodine in Evolution of Salivary Glands and in Oral Health

INTRODUCTION

Iodine (I) is the richest in electrons of the required elements in the animal diet, and as Iodide (I-) enters into the cells. Inorganic Iodide is necessary for all living animal cells, but only the vertebrates have the thyroid gland and its iodinated hormones. In humans, the total amount of Iodine is about 25-50 mg. About 50-70 % of total Iodine is non-hormonal and it is concentrated in extra-thyroidal tissues, where its biological role is still unknown. In 1985, Venturi has hypothesized that Iodide might have an ancestral antioxidant function in all I-concentrating cells from primitive marine algae to more recent terrestrial vertebrates [1-5 ]. In these cells iodide acts as an electron donor in the presence of H2O2 (Hydrogen-Peroxid) and peroxidases. The remaining iodine atom readily iodinates tyrosine, histidine or certain specific lipids, and so, neutralizes its own oxidant power.


IODINE, THYROXINE and EVOLUTION

When some primitive marine vertebrates started to emerge from the I-rich sea and transferred to I-deficient fresh water of estuaries and rivers and finally land, their diet became I-deficient and also harboured vegetable I-competitors such as nitrates , nitrites , thiocyanates, fluorides and some glycosides. About 400-500 million years ago (M/y/a), primitive Chordates started to use a new efficient follicular organ: the thyroid, as reservoir of iodine. During progressive slow adaptation to terrestrial life, the ancient chordates started to use the primitive, but not antagonized, T4 in order to transport antioxidant iodide into the peripherical cells. The remaining triiodothyronine (T3), the real active hormone, became active in the metamorphosis and thermogenesis for a better adaptation of the organisms to new terrestrial environment (fresh-water, atmosphere, gravity, temperature and diet). The new hormonal action of T3 was made possible by the formation of T3-receptors in the cells of vertebrates. Firstly, about 600-500 million years ago, in primitive Chordata appeared T3-receptors with a metamorphosing action and then, about 250-150 million years ago, in the birds and mammals appeared other T3-receptors with metabolic and thermogenetic actions. In waters the iodine concentration decreases step by step from sea-water to estuary (about 5 mg / L) and source of rivers (less than 0.2 mg / L in some Triassic mountain regions of northern Italy), and in parallel, salt-water fishes (herring) contain about 500-800 mg of iodine per kg compared to fresh-water trout about 20 mg per kg (4, 5). So, in terrestrial I-deficient fresh waters some trout and other salmonids (anadromous migra­tory fishes) may suffer thyroid hypertrophy or related metabolic disorders (4), as do some sharks in captivity. Youson and Sower (6, 7) reported that iodide-concentrating ability of the endostyle of sea lamprey was a critical factor in the evolution of metamorphosis and that the endostyle was replaced by a follicular thyroid, since post-metamorphic animals needed to store iodine following their invasion of freshwater. According to Manzon and Youson (8) in some anadromous migratory fishes (sea lamprey and salmonids), iodine and TH play a role in initiation of metamorphosis, which is induced by the decline in serum of TH. After metamorphosis, when these adult marine fishes die in fresh-water after reproducing, they release their iodides and selenium, and n-3 fatty acids (3), in the environment, where they have a favorable role in food for life and health of native animals, bringing back upstream from the sea to I-deficient areas these essential trace-elements (3, 4).


IODINE and SALIVARY GANDS

About 350 M/y/a the dry diet of terrestrial environment stimulated, firstly in anuran amphibians and after in reptiles [9] the primitive tongue and the formation, from I-concentrating ectodermic and endodermic cells of oral mucosa, of the primitive salivary glands, which maintain I-concentrating ability, and are able to solubilizating food substances. In anuran amphibian metamorphosis iodides and thyroxine are the most important factor inducing the spectacular apoptosis of cells of tail, gills, fins and gut. In fact, some important functions of saliva are: cleansing of the oral cavity, solubilization of food substances, bolus formation, facilitation of mastication and swallowing, food and bacterial clearance, dilution of detritus and lubrication of mucosa. Sodium iodide symporter (NIS) is the proteic transmembrane transporter of iodide into the cells (10). Salivary glands and gastric “iodide-pump” and NIS, are more primitive than the thyroidal ones, so have lower affinity for iodide and does not respond to more phylogenetically recent TSH (Thyrotropin). In pregnant mouse, the fetal oral and gastric mucosa shows iodine-concentrating ability earlier than fetal thyroid [11]. Gastro-salivary clearance and secretions of iodides are an important part of “gastro-intestinal cycle of iodides”, which constitutes about 23 % of iodides pool in the human body, that is important for the overall iodide economy [12]. Mammalians, as cows in their abomasum, have an efficient iodine recycling system via the oral-salivary and gastro-intestinal tract, which conserves iodine and can protect them against low dietary iodine [13-16]. The entero-thyroidal circulation of iodides seems mediated principally by salivary and gastric NIS. In the mammals and humans, dietary iodine is, by NIS, rapidly adsorbed as iodide (I-) from the small intestine. Several mammalian extrathyroidal non-follicular organs share the same gene expression of NIS and particularly salivary glands, stomach mucosa and lactating mammary gland [11, 17]. Thymus, epidermis, choroid plexus and articular, arterial and skeletal systems [11, 18] have I-concentrating ability too. The fact that 131-radioiodine is also detectable in radioautographies of oral mucosa and epidermal fur of rats after 14 days, strongly suggests formation of unknown structural iodocompounds and iodoproteins in some I-concentrating cells [17,18]. Salivary glands and saliva have highest and rapid I-concentrating capacity in the body, via an efficent NIS. According to Banerjee [19, 20] and De SK [21] the salivary glands and gastric mucosa has high ability to concentrate iodides and to form iodocompounds by peroxidases. The fact that mucous cells of some metastases from salivary glands and gastric cancers show I-concentrating ability might be interesting for a possible radiometabolic therapy [22]. The thyroidal and extrathyroidal I-concentration and NIS are inhibited by nitrates , nitrites , fluorides, thiocyanate, some glycosides, salt and also, paradoxically, by an excessive quantity of iodine. Excess of iodides impairs the iodide pump ( and NIS) and the cellular trophism of iodide-concentrating tissues, resulting in functional damage including the well-known Wolff-Chaikoff effect, which occurs in the thyroid even with a dosage just in excess of 2 mg, as well as degenerative and necrotic lesions in the iodide-concentrating tissues (thyroid, salivary gland and gastric mucosa). Inorganic iodine regulates the production of epidermal growth factor (EGF) in isolated thyroid cells, and controls DNA synthesis and cell proliferation [23]; this action might also occur in gastric mucosa and in salivary glands. EGF is a low-molecular-weight polypeptide first purified from the mouse submandibular gland, but since then found in many human tissues including submandibular gland, parotid gland. Salivary EGF plays an important physiological role in the maintenance of oro-esophageal and gastric tissue integrity. The biological effects of salivary EGF, and also esophageal derived EGF, include healing of ulcers, inhibition of gastric acid secretion, stimulation of DNA synthesis as well as mucosal protection from intraluminal injurious factors such as gastric acid, bile acids, pepsin, and trypsin and to physical, chemical and bacterial agents. The multiple functions of saliva relate both to its fluid characteristics and specific components. Banerjee reported iodination “in-vitro” of salivary and gastric proteins by peroxidase enzymes, and reported that salivary gland is one of the richest sources of peroxidases, which are similar to the lactoperoxidases [19, 20]. De SK et al. [21] investigated the role of peroxidase-catalyzed formation of iodotyrosines in submaxillary glands and stomach. Abbey et al. [ 24] reported that women incurred a fourfold-to-fivefold increased risk of a second primary Breast Cancer subsequent to the first primary salivary gland tumor. In October 7, 1999, the U.S.A. Committee of the House and Senate regarding "Marine Research" reported that " The Committee notes the unusually low incidence of cancer in marine sharks, skates, and rays and encourages basic research …that have the potential to inhibit disease processes in humans." The role of iodine in fishes has not been completely understood, but it has been demonstrated that iodine-deficient fresh-water fishes suffer of higher incidence of infective, parasitic, neoplastic, and atherosclerotic diseases than marine fishes [5].



IODINE , ORAL and DENTAL PATHOLOGY

In our I-deficient district of Montefeltro [1], before iodine-prophylaxis, comparison of decayed missing and filled teeth (DMFT index) in 12-year old children in 1980-1985, was 5.2, with a caries component of 89 % (Venturi, unpublished data) compared with the mean Italian values of 3.0 (in1985) and of the I-sufficient Finland of 1.2 (in 1991). Littleton and Frohlich [25] reported that twelve skeletal samples,from the Arabian Gulf have been used to trace differences in diet and subsistence patterns through an analysis of dental pathology. The skeletons date from 3,000 BC to AD 1,500 and cover a variety of geographical locations: off-shore islands, Eastern Arabia, and Oman. The dental conditions analyzed are attrition, caries, and ante-mortem tooth loss (AMTL). Results indicate four basic patterns of dental disease which, while not mutually exclusive, correspond to four basic subsistence patterns. Marine dependency (rich in iodine) in population, is indicated by severe attrition, low caries rates, and a lack of AMTL. The second group of dental diseases-moderate attrition, low rates of caries, and low-moderate rates of AMTL affects populations subsisting on a mixture of pastoralism or fishing and agriculture. Mixed farming populations experienced low-moderate attrition, high rates of caries and abscessing due to caries, and severe AMTL. The final group of dental diseases affects inland populations practicing intensive gardening. These groups experienced slight attrition, high rates of caries, and severe AMTL. Sealy et al. [26] reported that incidences of dental caries are presented for three groups of prehistoric human skeletons from different regions of the Cape Province, South Africa. The isotopic analyses of bone collagen demonstrate the importance of (I-rich) marine foods in the diet and vary through time. The incidence of dental caries ranges from 0% among heavily marine-dependent individuals from the south-western Cape coast, to 17.7% among skeletons from an archaeological site on the south coast. The authors reported that the extremely high incidence of caries in population may be related to lack of fluoride in the water. Also overall cancer incidence in I-rich marine fishes is lower than in fresh-water fishes. Elvery et al. [27] in an anthropological investigation of the Ngaraangbal Aboriginal Tribe's, a hunter-gatherer population, at Broadbeach, Australia, the caries prevalence (0.8%) was very low. These results support the proposal that the Ngaraangbal tribe with a diet that included marine foods. In fact, it is rare to find oral diseases, as well as malignant tumors, in I-rich marine fishes.
Many researchers (28-31) and Wharton [32] reported that immunodeficiency and malnutrition in adolescence and iodine deficiency and dental caries are associated. In 1939, Hardgrove [33] reported that “in his community (Fond du Lac, Wis, USA), since the beginning of administration of iodine to prevent goitre, children have less caries. Iodine seems to increase resistance to caries, retarding the process and reducing its incidence.” Recently Abnet et al. showed a statistical correlation between I-deficient goitre and gastric cancer (34) and between gastric cancer and tooth loss in a Chinese cohort of the Linxian General Population Nutrition Intervention Trial ( 35, 36).

In conclusion, we believe that the antioxidant, apoptosis-inductor and presumed antitumour activities of iodide might be useful in oral health and in prevention of some extra-thyroidal and salivary gland cancers.

drink more water.

Are you salt loading? Sometimes headaches can be avoided altogether with proper salt loading. And salt loading decreases all kinds of side effects, as well as tolerance to iodine.

As far as the dry mouth - I have noticed a general drying with iodine. I wonder if it is connected to mucous problems, which I have had in the past, as it is the same type of dryness as with an antihistamine. As far as detox symptoms go, we are affected by wherever we are weak. I have found that really large doses of vitamin A and cod liver oil help my mucous membrane problems.

Taking Iodine breaks helps too. I take one day a week.
